| 53af7f21 | 513 | <h2><a id="introduction">Introduction</a></h2> |
| 798d6e29 MS |
514 | <p>CUPS provides the "cups" library to talk to the different parts of CUPS and with Internet Printing Protocol (IPP) printers. The "cups" library functions are accessed by including the <code><cups/cups.h></code> header.</p> |
| 515 | <p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows clients (applications) to communicate with a server (the scheduler, printers, etc.) to get a list of destinations, send print jobs, and so forth. You identify which server you want to communicate with using a pointer to the opaque structure <code>http_t</code>. The <code>CUPS_HTTP_DEFAULT</code> constant can be used when you want to talk to the CUPS scheduler.</p> | |
| 53af7f21 | 516 | <h3><a id="guidelines">Guidelines</a></h3> |
| 798d6e29 MS |
517 | <p>When writing software that uses the "cups" library:</p> |
| 518 | <ul> | |
| 519 | <li>Do not use undocumented or deprecated APIs,</li> | |
| 520 | <li>Do not rely on pre-configured printers,</li> | |
| 521 | <li>Do not assume that printers support specific features or formats, and</li> | |
| 522 | <li>Do not rely on implementation details (PPDs, etc.)</li> | |
| 523 | </ul> | |
| 524 | <p>CUPS is designed to insulate users and developers from the implementation details of printers and file formats. The goal is to allow an application to supply a print file in a standard format with the user intent ("print four copies, two-sided on A4 media, and staple each copy") and have the printing system manage the printer communication and format conversion needed.</p> | |
| 525 | <p>Similarly, printer and job management applications can use standard query operations to obtain the status information in a common, generic form and use standard management operations to control the state of those printers and jobs.</p> | |
| 53af7f21 | 526 | <h3><a id="terms-used-in-this-document">Terms Used in This Document</a></h3> |
| 9c44e2cb | 527 | <p>A <em>Destination</em> is a printer or print queue that accepts print jobs. A <em>Print</em> <em>Job</em> is one or more documents that are processed by a destination using options supplied when creating the job. A <em>Document</em> is a file (JPEG image, PDF file, etc.) suitable for printing. An <em>Option</em> controls some aspect of printing, such as the media used. <em>Media</em> is the sheets or roll that is printed on. An <em>Attribute</em> is an option encoded for an Internet Printing Protocol (IPP) request.</p> |
| 53af7f21 | 528 | <h3><a id="compiling-programs-that-use-the-cups-api">Compiling Programs That Use the CUPS API</a></h3> |
| 798d6e29 MS |
529 | <p>The CUPS libraries can be used from any C, C++, or Objective C program. The method of compiling against the libraries varies depending on the operating system and installation of CUPS. The following sections show how to compile a simple program (shown below) in two common environments.</p> |
| 530 | <p>The following simple program lists the available destinations:</p> | |
| 531 | <pre><code>#include <stdio.h> | |
| 532 | #include <cups/cups.h> | |
| 533 | ||
| 534 | int print_dest(void *user_data, unsigned flags, cups_dest_t *dest) | |
| 535 | { | |
| 536 | if (dest->instance) | |
| 537 | printf("%s/%s\n", dest->name, dest->instance); | |
| 538 | else | |
| 539 | puts(dest->name); | |
| 540 | ||
| 541 | return (1); | |
| 542 | } | |
| 543 | ||
| 544 | int main(void) | |
| 545 | { | |
| 546 | cupsEnumDests(CUPS_DEST_FLAGS_NONE, 1000, NULL, 0, 0, print_dest, NULL); | |
| 547 | ||
| 548 | return (0); | |
| 549 | } | |
| 550 | </code></pre> | |
| 53af7f21 | 551 | <h4><a id="compiling-with-xcode">Compiling with Xcode</a></h4> |
| 9c44e2cb MS |
552 | <p>In Xcode, choose <em>New</em> <em>Project...</em> from the <em>File</em> menu (or press SHIFT+CMD+N), then select the <em>Command</em> <em>Line</em> <em>Tool</em> under the macOS Application project type. Click <em>Next</em> and enter a name for the project, for example "firstcups". Click <em>Next</em> and choose a project directory. The click <em>Next</em> to create the project.</p> |
| 553 | <p>In the project window, click on the <em>Build</em> <em>Phases</em> group and expand the <em>Link</em> <em>Binary</em> <em>with</em> <em>Libraries</em> section. Click <em>+</em>, type "libcups" to show the library, and then double-click on <code>libcups.tbd</code>.</p> | |
| 798d6e29 | 554 | <p>Finally, click on the <code>main.c</code> file in the sidebar and copy the example program to the file. Build and run (CMD+R) to see the list of destinations.</p> |
| 53af7f21 | 555 | <h4><a id="compiling-with-gcc">Compiling with GCC</a></h4> |
| 798d6e29 MS |
556 | <p>From the command-line, create a file called <code>sample.c</code> using your favorite editor, copy the example to this file, and save. Then run the following command to compile it with GCC and run it:</p> |
| 557 | <pre><code>gcc -o simple `cups-config --cflags` simple.c `cups-config --libs` | |
| 558 | ./simple | |
| 559 | </code></pre> | |
| 9c44e2cb | 560 | <p>The <code>cups-config</code> command provides the compiler flags (<code>cups-config --cflags</code>) and libraries (<code>cups-config --libs</code>) needed for the local system.</p> |
| 53af7f21 | 561 | <h2><a id="working-with-destinations">Working with Destinations</a></h2> |
| 9c44e2cb | 562 | <p>Destinations, which in CUPS represent individual printers or classes (collections or pools) of printers, are represented by the <code>cups_dest_t</code> structure which includes the name (<code>name</code>), instance (<code>instance</code>, saved options/settings), whether the destination is the default for the user (<code>is_default</code>), and the options and basic information associated with that destination (<code>num_options</code> and <code>options</code>).</p> |
| 798d6e29 | 563 | <p>Historically destinations have been manually maintained by the administrator of a system or network, but CUPS also supports dynamic discovery of destinations on the current network.</p> |
| 53af7f21 | 564 | <h3><a id="finding-available-destinations">Finding Available Destinations</a></h3> |
| 798d6e29 MS |
565 | <p>The <code>cupsEnumDests</code> function finds all of the available destinations:</p> |
| 566 | <pre><code> int | |
| 567 | cupsEnumDests(unsigned flags, int msec, int *cancel, | |
| 568 | cups_ptype_t type, cups_ptype_t mask, | |
| 569 | cups_dest_cb_t cb, void *user_data) | |
| 570 | </code></pre> | |
| 571 | <p>The <code>flags</code> argument specifies enumeration options, which at present must be <code>CUPS_DEST_FLAGS_NONE</code>.</p> | |
| 572 | <p>The <code>msec</code> argument specifies the maximum amount of time that should be used for enumeration in milliseconds - interactive applications should keep this value to 5000 or less when run on the main thread.</p> | |
| 573 | <p>The <code>cancel</code> argument points to an integer variable that, when set to a non-zero value, will cause enumeration to stop as soon as possible. It can be <code>NULL</code> if not needed.</p> | |
| 53af7f21 | 574 | <p>The <code>type</code> and <code>mask</code> arguments are bitfields that allow the caller to filter the destinations based on categories and/or capabilities. The destination's "printer-type" value is masked by the <code>mask</code> value and compared to the <code>type</code> value when filtering. For example, to only enumerate destinations that are hosted on the local system, pass <code>CUPS_PRINTER_LOCAL</code> for the <code>type</code> argument and <code>CUPS_PRINTER_DISCOVERED</code> for the <code>mask</code> argument. The following constants can be used for filtering:</p> |
| 798d6e29 MS |
575 | <ul> |
| 576 | <li><code>CUPS_PRINTER_CLASS</code>: A collection of destinations.</li> | |
| 577 | <li><code>CUPS_PRINTER_FAX</code>: A facsimile device.</li> | |
| 53af7f21 MS |
578 | <li><code>CUPS_PRINTER_LOCAL</code>: A local printer or class. This constant has the value 0 (no bits set) and is only used for the <code>type</code> argument and is paired with the <code>CUPS_PRINTER_REMOTE</code> or <code>CUPS_PRINTER_DISCOVERED</code> constant passed in the <code>mask</code> argument.</li> |
| 579 | <li><code>CUPS_PRINTER_REMOTE</code>: A remote (shared) printer or class.</li> | |
| 580 | <li><code>CUPS_PRINTER_DISCOVERED</code>: An available network printer or class.</li> | |
| 798d6e29 MS |
581 | <li><code>CUPS_PRINTER_BW</code>: Can do B&W printing.</li> |
| 582 | <li><code>CUPS_PRINTER_COLOR</code>: Can do color printing.</li> | |
| 583 | <li><code>CUPS_PRINTER_DUPLEX</code>: Can do two-sided printing.</li> | |
| 584 | <li><code>CUPS_PRINTER_STAPLE</code>: Can staple output.</li> | |

| 798d6e29 MS |
691 | </ul> |
| 692 | <p>Use the <code>cupsGetOption</code> function to retrieve the value. For example, the following code gets the make and model of a destination:</p> | |

791 | <p>The finishings and media options also support queries for the ready, or loaded, values. For example, a printer may have punch and staple finishers installed but be out of staples - the supported values will list both punch and staple finishing processes but the ready values will only list the punch processes. Similarly, a printer may support hundreds of different sizes of media but only have a single size loaded at any given time - the ready values are limited to the media that is actually in the printer.</p> |

| 835 | </code></pre> | |
| 836 | <p>The <code>media</code>, <code>width</code>, and <code>length</code> arguments specify the size to lookup. The <code>flags</code> argument specifies a bitfield controlling various lookup options:</p> | |
| 837 | <ul> | |
| 838 | <li><code>CUPS_MEDIA_FLAGS_DEFAULT</code>: Find the closest size supported by the printer.</li> | |
| 839 | <li><code>CUPS_MEDIA_FLAGS_BORDERLESS</code>: Find a borderless size.</li> | |

| 925 | <p>The <code>title</code> argument specifies a name for the print job such as "My Document". The <code>num_options</code> and <code>options</code> arguments specify the options for the print job which are allocated using the <code>cupsAddOption</code> function.</p> | |
| 926 | <p>When successful, the job's numeric identifier is stored in the integer pointed to by the <code>job_id</code> argument and <code>IPP_STATUS_OK</code> is returned. Otherwise, an IPP error status is returned.</p> | |
| 927 | <p>For example, the following code creates a new job that will print 42 copies of a two-sided US Letter document:</p> | |

998 | <h2><a id="sending-ipp-requests">Sending IPP Requests</a></h2> |
| 999 | <p>CUPS provides a rich API for sending IPP requests to the scheduler or printers, typically from management or utility applications whose primary purpose is not to send print jobs.</p> | |
| 1000 | <h3><a id="connecting-to-the-scheduler-or-printer">Connecting to the Scheduler or Printer</a></h3> | |
| 1001 | <p>The connection to the scheduler or printer is represented by the HTTP connection type <code>http_t</code>. The <code>cupsConnectDest</code> function connects to the scheduler or printer associated with the destination:</p> | |
| 1002 | <pre><code>http_t * | |
| 1003 | cupsConnectDest(cups_dest_t *dest, unsigned flags, int msec, | |
| 1004 | int *cancel, char *resource, | |
| 1005 | size_t resourcesize, cups_dest_cb_t cb, | |
| 1006 | void *user_data); | |
| 1007 | </code></pre> | |
| 1008 | <p>The <code>dest</code> argument specifies the destination to connect to.</p> | |
| 1009 | <p>The <code>flags</code> argument specifies whether you want to connect to the scheduler (<code>CUPS_DEST_FLAGS_NONE</code>) or device/printer (<code>CUPS_DEST_FLAGS_DEVICE</code>) associated with the destination.</p> | |
| 1010 | <p>The <code>msec</code> argument specifies how long you are willing to wait for the connection to be established in milliseconds. Specify a value of <code>-1</code> to wait indefinitely.</p> | |
| 1011 | <p>The <code>cancel</code> argument specifies the address of an integer variable that can be set to a non-zero value to cancel the connection. Specify a value of <code>NULL</code> to not provide a cancel variable.</p> | |
| 1012 | <p>The <code>resource</code> and <code>resourcesize</code> arguments specify the address and size of a character string array to hold the path to use when sending an IPP request.</p> | |
| 1013 | <p>The <code>cb</code> and <code>user_data</code> arguments specify a destination callback function that returns 1 to continue connecting or 0 to stop. The destination callback work the same way as the one used for the <code>cupsEnumDests</code> function.</p> | |
| 1014 | <p>On success, a HTTP connection is returned that can be used to send IPP requests and get IPP responses.</p> | |
| 1015 | <p>For example, the following code connects to the printer associated with a destination with a 30 second timeout:</p> | |
| 1016 | <pre><code>char resource[256]; | |
| 1017 | http_t *http = cupsConnectDest(dest, CUPS_DEST_FLAGS_DEVICE, | |
| 1018 | 30000, NULL, resource, | |
| 1019 | sizeof(resource), NULL, NULL); | |
| 1020 | </code></pre> | |
| 1021 | <h3><a id="creating-an-ipp-request">Creating an IPP Request</a></h3> | |
| 1022 | <p>IPP requests are represented by the IPP message type <code>ipp_t</code> and each IPP attribute in the request is representing using the type <code>ipp_attribute_t</code>. Each IPP request includes an operation code (<code>IPP_OP_CREATE_JOB</code>, <code>IPP_OP_GET_PRINTER_ATTRIBUTES</code>, etc.) and a 32-bit integer identifier.</p> | |
| 1023 | <p>The <code>ippNewRequest</code> function creates a new IPP request:</p> | |
| 1024 | <pre><code>ipp_t * | |
| 1025 | ippNewRequest(ipp_op_t op); | |
| 1026 | </code></pre> | |
| 1027 | <p>The <code>op</code> argument specifies the IPP operation code for the request. For example, the following code creates an IPP Get-Printer-Attributes request:</p> | |
| 1028 | <pre><code>ipp_t *request = ippNewRequest(IPP_OP_GET_PRINTER_ATTRIBUTES); | |
| 1029 | </code></pre> | |
| 1030 | <p>The request identifier is automatically set to a unique value for the current process.</p> | |
| 1031 | <p>Each IPP request starts with two IPP attributes, "attributes-charset" and "attributes-natural-language", followed by IPP attribute(s) that specify the target of the operation. The <code>ippNewRequest</code> automatically adds the correct "attributes-charset" and "attributes-natural-language" attributes, but you must add the target attribute(s). For example, the following code adds the "printer-uri" attribute to the IPP Get-Printer-Attributes request to specify which printer is being queried:</p> | |
| 1032 | <pre><code>const char *printer_uri = cupsGetOption("device-uri", | |
| 1033 | dest->num_options, | |
| 1034 | dest->options); | |
| 1035 | ||
| 1036 | ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_URI, | |
| 1037 | "printer-uri", NULL, printer_uri); | |
| 1038 | </code></pre> | |
| 1039 | <blockquote> | |
| 1040 | <p>Note: If we wanted to query the scheduler instead of the device, we would look up the "printer-uri-supported" option instead of the "device-uri" value.</p> | |
| 1041 | </blockquote> | |
| 1042 | <p>The <code>ippAddString</code> function adds the "printer-uri" attribute the the IPP request. The <code>IPP_TAG_OPERATION</code> argument specifies that the attribute is part of the operation. The <code>IPP_TAG_URI</code> argument specifies that the value is a Universal Resource Identifier (URI) string. The <code>NULL</code> argument specifies there is no language (English, French, Japanese, etc.) associated with the string, and the <code>printer_uri</code> argument specifies the string value.</p> | |
| 1043 | <p>The IPP Get-Printer-Attributes request also supports an IPP attribute called "requested-attributes" that lists the attributes and values you are interested in. For example, the following code requests the printer state attributes:</p> | |
| 1044 | <pre><code>static const char * const requested_attributes[] = | |
| 1045 | { | |
| 1046 | "printer-state", | |
| 1047 | "printer-state-message", | |
| 1048 | "printer-state-reasons" | |
| 1049 | }; | |
| 1050 | ||
| 1051 | ippAddStrings(request, IPP_TAG_OPERATION, IPP_TAG_KEYWORD, | |
| 1052 | "requested-attributes", 3, NULL, | |
| 1053 | requested_attributes); | |
| 1054 | </code></pre> | |
| 1055 | <p>The <code>ippAddStrings</code> function adds an attribute with one or more strings, in this case three. The <code>IPP_TAG_KEYWORD</code> argument specifies that the strings are keyword values, which are used for attribute names. All strings use the same language (<code>NULL</code>), and the attribute will contain the three strings in the array <code>requested_attributes</code>.</p> | |
| 1056 | <p>CUPS provides many functions to adding attributes of different types:</p> | |
| 1057 | <ul> | |
| 1058 | <li><code>ippAddBoolean</code> adds a boolean (<code>IPP_TAG_BOOLEAN</code>) attribute with one value.</li> | |
| 1059 | <li><code>ippAddInteger</code> adds an enum (<code>IPP_TAG_ENUM</code>) or integer (<code>IPP_TAG_INTEGER</code>) attribute with one value.</li> | |
| 1060 | <li><code>ippAddIntegers</code> adds an enum or integer attribute with one or more values.</li> | |
| 1061 | <li><code>ippAddOctetString</code> adds an octetString attribute with one value.</li> | |
| 1062 | <li><code>ippAddOutOfBand</code> adds a admin-defined (<code>IPP_TAG_ADMINDEFINE</code>), default (<code>IPP_TAG_DEFAULT</code>), delete-attribute (<code>IPP_TAG_DELETEATTR</code>), no-value (<code>IPP_TAG_NOVALUE</code>), not-settable (<code>IPP_TAG_NOTSETTABLE</code>), unknown (<code>IPP_TAG_UNKNOWN</code>), or unsupported (<code>IPP_TAG_UNSUPPORTED_VALUE</code>) out-of-band attribute.</li> | |
| 1063 | <li><code>ippAddRange</code> adds a rangeOfInteger attribute with one range.</li> | |
| 1064 | <li><code>ippAddRanges</code> adds a rangeOfInteger attribute with one or more ranges.</li> | |
| 1065 | <li><code>ippAddResolution</code> adds a resolution attribute with one resolution.</li> | |
| 1066 | <li><code>ippAddResolutions</code> adds a resolution attribute with one or more resolutions.</li> | |
| 1067 | <li><code>ippAddString</code> adds a charset (<code>IPP_TAG_CHARSET</code>), keyword (<code>IPP_TAG_KEYWORD</code>), mimeMediaType (<code>IPP_TAG_MIMETYPE</code>), name (<code>IPP_TAG_NAME</code> and <code>IPP_TAG_NAMELANG</code>), naturalLanguage (<code>IPP_TAG_NATURAL_LANGUAGE</code>), text (<code>IPP_TAG_TEXT</code> and <code>IPP_TAG_TEXTLANG</code>), uri (<code>IPP_TAG_URI</code>), or uriScheme (<code>IPP_TAG_URISCHEME</code>) attribute with one value.</li> | |
| 1068 | <li><code>ippAddStrings</code> adds a charset, keyword, mimeMediaType, name, naturalLanguage, text, uri, or uriScheme attribute with one or more values.</li> | |
| 1069 | </ul> | |
| 1070 | <h3><a id="sending-the-ipp-request">Sending the IPP Request</a></h3> | |
| 1071 | <p>Once you have created the IPP request, you can send it using the <code>cupsDoRequest</code> function. For example, the following code sends the IPP Get-Printer-Attributes request to the destination and saves the response:</p> | |
| 1072 | <pre><code>ipp_t *response = cupsDoRequest(http, request, resource); | |
| 1073 | </code></pre> | |
| 1074 | <p>For requests like Send-Document that include a file, the <code>cupsDoFileRequest</code> function should be used:</p> | |
| 1075 | <pre><code>ipp_t *response = cupsDoFileRequest(http, request, resource, | |
| 1076 | filename); | |
| 1077 | </code></pre> | |
| 1078 | <p>Both <code>cupsDoRequest</code> and <code>cupsDoFileRequest</code> free the IPP request. If a valid IPP response is received, it is stored in a new IPP message (<code>ipp_t</code>) and returned to the caller. Otherwise <code>NULL</code> is returned.</p> | |
| 1079 | <p>The status from the most recent request can be queried using the <code>cupsLastError</code> function, for example:</p> | |
| 1080 | <pre><code>if (cupsLastError() >= IPP_STATUS_ERROR_BAD_REQUEST) | |
| 1081 | { | |
| 1082 | /* request failed */ | |
| 1083 | } | |
| 1084 | </code></pre> | |
| 1085 | <p>A human-readable error message is also available using the <code>cupsLastErrorString</code> function:</p> | |
| 1086 | <pre><code>if (cupsLastError() >= IPP_STATUS_ERROR_BAD_REQUEST) | |
| 1087 | { | |
| 1088 | /* request failed */ | |
| 1089 | printf("Request failed: %s\n", cupsLastErrorString()); | |
| 1090 | } | |
| 1091 | </code></pre> | |
| 1092 | <h3><a id="processing-the-ipp-response">Processing the IPP Response</a></h3> | |
| 1093 | <p>Each response to an IPP request is also an IPP message (<code>ipp_t</code>) with its own IPP attributes (<code>ipp_attribute_t</code>) that includes a status code (<code>IPP_STATUS_OK</code>, <code>IPP_STATUS_ERROR_BAD_REQUEST</code>, etc.) and the corresponding 32-bit integer identifier from the request.</p> | |
| 1094 | <p>For example, the following code finds the printer state attributes and prints their values:</p> | |
| 1095 | <pre><code>ipp_attribute_t *attr; | |
| 1096 | ||
| 1097 | if ((attr = ippFindAttribute(response, "printer-state", | |
| 1098 | IPP_TAG_ENUM)) != NULL) | |
| 1099 | { | |
| 1100 | printf("printer-state=%s\n", | |
| 1101 | ippTagString("printer-state", ippGetInteger(attr, 0))); | |
| 1102 | } | |
| 1103 | else | |
| 1104 | puts("printer-state=unknown"); | |
| 1105 | ||
| 1106 | if ((attr = ippFindAttribute(response, "printer-state-message", | |
| 1107 | IPP_TAG_TEXT)) != NULL) | |
| 1108 | { | |
| 1109 | printf("printer-state-message=\"%s\"\n", | |
| 1110 | ippGetString(attr, 0, NULL))); | |
| 1111 | } | |
| 1112 | ||
| 1113 | if ((attr = ippFindAttribute(response, "printer-state-reasons", | |
| 1114 | IPP_TAG_KEYWORD)) != NULL) | |
| 1115 | { | |
| 1116 | int i, count = ippGetCount(attr); | |
| 1117 | ||
| 1118 | puts("printer-state-reasons="); | |
| 1119 | for (i = 0; i < count; i ++) | |
| 1120 | printf(" %s\n", ippGetString(attr, i, NULL))); | |
| 1121 | } | |
| 1122 | </code></pre> | |
| 1123 | <p>The <code>ippGetCount</code> function returns the number of values in an attribute.</p> | |
| 1124 | <p>The <code>ippGetInteger</code> and <code>ippGetString</code> functions return a single integer or string value from an attribute.</p> | |
| 1125 | <p>The <code>ippTagString</code> function converts a enum value to its keyword (string) equivalent.</p> | |
| 1126 | <p>Once you are done using the IPP response message, free it using the <code>ippDelete</code> function:</p> | |
| 1127 | <pre><code>ippDelete(response); | |
| 1128 | </code></pre> | |
| 1129 | <h3><a id="authentication">Authentication</a></h3> | |
| 1130 | <p>CUPS normally handles authentication through the console. GUI applications should set a password callback using the <code>cupsSetPasswordCB2</code> function:</p> | |
| 1131 | <pre><code>void | |
| 1132 | cupsSetPasswordCB2(cups_password_cb2_t cb, void *user_data); | |
| 1133 | </code></pre> | |
| 1134 | <p>The password callback will be called when needed and is responsible for setting the current user name using <code>cupsSetUser</code> and returning a string:</p> | |
| 1135 | <pre><code>const char * | |
| 1136 | cups_password_cb2(const char *prompt, http_t *http, | |
| 1137 | const char *method, const char *resource, | |
| 1138 | void *user_data); | |
| 1139 | </code></pre> | |
| 1140 | <p>The <code>prompt</code> argument is a string from CUPS that should be displayed to the user.</p> | |
| 1141 | <p>The <code>http</code> argument is the connection hosting the request that is being authenticated. The password callback can call the <code>httpGetField</code> and <code>httpGetSubField</code> functions to look for additional details concerning the authentication challenge.</p> | |
| 1142 | <p>The <code>method</code> argument specifies the HTTP method used for the request and is typically "POST".</p> | |
| 1143 | <p>The <code>resource</code> argument specifies the path used for the request.</p> | |
| 1144 | <p>The <code>user_data</code> argument provides the user data pointer from the <code>cupsSetPasswordCB2</code> call.</p> | |

1540 | <p class="discussion">Destinations are enumerated from one or more sources. The callback function |
| 1541 | receives the <code>user_data</code> pointer and the destination pointer which can | |
| 1542 | be used as input to the <a href="#cupsCopyDest"><code>cupsCopyDest</code></a> function. The function must | |

| 1548 | destinations that are available but have not yet been added locally.<br> | |
