523 | <h2 class='title'><a name='OVERVIEW'>Overview</a></h2> |
| 524 | ||
| 525 | <p>The CUPS API provides the convenience functions needed to support | |
| 526 | applications, filters, printer drivers, and backends that need to interface | |
| 527 | with the CUPS scheduler.</p> | |
| ef416fc2 | 528 | |
| 568fa3fa MS |
529 | <h3><a name='CLIENTS_AND_SERVERS'>Clients and Servers</a></h3> |
| 530 | ||
| 531 | <p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows | |
| 532 | clients (applications) to communicate with a server (the scheduler) to get a | |
| 533 | list of printers, send print jobs, and so forth. You identify which server | |
| 534 | you want to communicate with using a pointer to the opaque structure | |
| 535 | <code>http_t</code>. All of the examples in this document use the | |
| 536 | <code>CUPS_HTTP_DEFAULT</code> constant, referring to the default connection | |
| 537 | to the scheduler. The <a href='api-httpipp.html' target='_top'>HTTP and IPP | |
| 538 | APIs</a> document provides more information on server connections.</p> | |

| ecdc0628 | 541 | |
| 5a738aea MS |
542 | <p>Printers and classes (collections of printers) are accessed through |
| 543 | the <a href="#cups_dest_t"><code>cups_dest_t</code></a> structure which | |
| 544 | includes the name (<code>name</code>), instance (<code>instance</code> - | |
| 568fa3fa MS |
545 | a way of selecting certain saved options/settings), and the options and |
| 546 | attributes associated with that destination (<code>num_options</code> and | |
| 5a738aea MS |
547 | <code>options</code>). Destinations are created using the |
| 548 | <a href="#cupsGetDests"><code>cupsGetDests</code></a> function and freed | |
| 549 | using the <a href='#cupsFreeDests'><code>cupsFreeDests</code></a> function. | |
| 550 | The <a href='#cupsGetDest'><code>cupsGetDest</code></a> function finds a | |
| 551 | specific destination for printing:</p> | |
| ef416fc2 | 552 | |
| 5a738aea MS |
553 | <pre class='example'> |

| 5a738aea MS |
565 | <p>Passing <code>NULL</code> to |
| 566 | <a href='#cupsGetDest'><code>cupsGetDest</code></a> for the destination name | |
| 567 | will return the default destination. Similarly, passing a <code>NULL</code> | |
| 568 | instance will return the default instance for that destination.</p> | |

| 631 | <h3><a name='OPTIONS'>Options</a></h3> | |
| 632 | ||
| 633 | <p>Options are stored in arrays of | |
| 634 | <a href='#cups_option_t'><code>cups_option_t</code></a> structures. Each | |
| 635 | option has a name (<code>name</code>) and value (<code>value</code>) | |
| 636 | associated with it. The <a href='#cups_dest_t'><code>cups_dest_t</code></a> | |
| 637 | <code>num_options</code> and <code>options</code> members contain the | |
| 638 | default options for a particular destination, along with several informational | |
| 639 | attributes about the destination as shown in <a href='#TABLE1'>Table 1</a>. | |
| 640 | The <a href='#cupsGetOption'><code>cupsGetOption</code></a> function gets | |
| 641 | the value for the named option. For example, the following code lists the | |
| 642 | available destinations and their human-readable descriptions:</p> | |
| 643 | ||
| 644 | <pre class='example'> | |
| 645 | #include <cups/cups.h> | |

| 661 | </pre> | |
| 662 | ||
| 663 | <p>You can create your own option arrays using the | |
| 664 | <a href='#cupsAddOption'><code>cupsAddOption</code></a> function, which | |
| 665 | adds a single named option to an array:</p> | |
| 666 | ||
| 667 | <pre class='example'> | |
| 668 | #include <cups/cups.h> | |
| 669 | ||
| 670 | int num_options = 0; | |

| 679 | /* This replaces the first option we added */ | |
| 680 | num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "new value", num_options, &options); | |
| 681 | </pre> | |
| 682 | ||
| 683 | <p>Use a <code>for</code> loop to copy the options from a destination:</p> | |
| 684 | ||
| 685 | <pre class='example'> | |
| 686 | #include <cups/cups.h> | |
| 687 | ||
| 688 | int i; | |

| 695 | num_options, &options); | |
| 5a738aea MS |
696 | </pre> |
| 697 | ||
| 698 | <p>Use the <a href='#cupsFreeOptions'><code>cupsFreeOptions</code></a> | |
| 699 | function to free the options array when you are done using it:</p> | |
| 700 | ||
| 701 | <pre class='example'> | |
| 702 | <a href='#cupsFreeOptions'>cupsFreeOptions</a>(num_options, options); | |

| 704 | ||
| 705 | <h3><a name='PRINT_JOBS'>Print Jobs</a></h3> | |
| 706 | ||
| 707 | <p>Print jobs are identified by a locally-unique job ID number from 1 to | |
| 708 | 2<sup>31</sup>-1 and have options and one or more files for printing to a | |
| 709 | single destination. The <a href='#cupsPrintFile'><code>cupsPrintFile</code></a> | |
| 710 | function creates a new job with one file. The following code prints the CUPS | |
| 711 | test page file:</p> | |
| 712 | ||
| 713 | <pre class='example'> | |
| 714 | #include <cups/cups.h> | |

| 723 | "Test Print", num_options, options); | |
| 5a738aea MS |
724 | </pre> |
| 725 | ||
| 726 | <p>The <a href='#cupsPrintFiles'><code>cupsPrintFiles</code></a> function | |
| 727 | creates a job with multiple files. The files are provided in a | |
| 728 | <code>char *</code> array:</p> | |
| 729 | ||
| 730 | <pre class='example'> | |
| 731 | #include <cups/cups.h> | |
| 732 | ||
| 733 | <a href='#cups_dest_t'>cups_dest_t</a> *dest; | |

| 735 | <a href='#cups_option_t'>cups_option_t</a> *options; | |
| 736 | int job_id; | |
| 737 | char *files[3] = { "file1.pdf", "file2.pdf", "file3.pdf" }; | |

| 739 | /* Print three files */ | |
| 740 | job_id = <a href='#cupsPrintFiles'>cupsPrintFiles</a>(dest->name, 3, files, "Test Print", num_options, options); | |
| 741 | </pre> | |
| 742 | ||
| 743 | <p>Finally, the <a href='#cupsCreateJob'><code>cupsCreateJob</code></a> | |
| 744 | function creates a new job with no files in it. Files are added using the | |

865 | #include <cups/cups.h> |

| 873 | <h3><a name='ERROR_HANDLING'>Error Handling</a></h3> | |
| 874 | ||
| 875 | <p>If any of the CUPS API printing functions returns an error, the reason for | |
| 876 | that error can be found by calling the | |
| 877 | <a href='#cupsLastError'><code>cupsLastError</code></a> and | |
| 878 | <a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> functions. | |
| 879 | <a href='#cupsLastError'><code>cupsLastError</code></a> returns the last IPP | |
| 880 | error code | |
| 881 | (<a href='api-httpipp.html#ipp_status_t'><code>ipp_status_t</code></a>) | |
| 882 | that was encountered, while | |
| 883 | <a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> returns | |
| 884 | a (localized) human-readable string that can be shown to the user. For example, | |
| 885 | if any of the job creation functions returns a job ID of 0, you can use | |
| 886 | <a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> to show | |
| 887 | the reason why the job could not be created:</p> | |
| 888 | ||
| 889 | <pre class='example'> | |
| 890 | #include <cups/cups.h> | |
| 891 | ||
| 892 | int job_id; | |

| 898 | <h3><a name='PASSWORDS_AND_AUTHENTICATION'>Passwords and Authentication</a></h3> | |
| 899 | ||
| 900 | <p>CUPS supports authentication of any request, including submission of print | |
| 901 | jobs. The default mechanism for getting the username and password is to use the | |
| 902 | login user and a password from the console.</p> | |
| 903 | ||
| 904 | <p>To support other types of applications, in particular Graphical User | |
| 905 | Interfaces ("GUIs"), the CUPS API provides functions to set the default | |
| 906 | username and to register a callback function that returns a password string.</p> | |
| 907 | ||
| 908 | <p>The <a href="#cupsSetPasswordCB"><code>cupsSetPasswordCB</code></a> | |
| 909 | function is used to set a password callback in your program. Only one | |
| 910 | function can be used at any time.</p> | |
| 911 | ||
| 912 | <p>The <a href="#cupsSetUser"><code>cupsSetUser</code></a> function sets the | |
| 913 | current username for authentication. This function can be called by your | |
| 914 | password callback function to change the current username as needed.</p> | |
| 915 | ||
| 916 | <p>The following example shows a simple password callback that gets a | |
| 917 | username and password from the user:</p> | |
| 918 | ||
| 919 | <pre class='example'> | |
| 920 | #include <cups/cups.h> | |
| 921 | ||
| 922 | const char * | |
| 923 | my_password_cb(const char *prompt) | |
| 924 | { | |
| 925 | char user[65]; | |
| 926 | ||
| 927 | ||
| 928 | puts(prompt); | |
| 929 | ||
| 930 | /* Get a username from the user */ | |
| 931 | printf("Username: "); | |
| 932 | if (fgets(user, sizeof(user), stdin) == NULL) | |
| 933 | return (NULL); | |
| 934 | ||
| 935 | /* Strip the newline from the string and set the user */ | |
| 936 | user[strlen(user) - 1] = '\0'; | |
| 937 | ||
| 938 | <a href='#cupsSetUser'>cupsSetUser</a>(user); | |
| 939 | ||
| 940 | /* Use getpass() to ask for the password... */ | |
| 941 | return (getpass("Password: ")); | |
| 942 | } | |
| 943 | ||
| 944 | <a href='#cupsSetPasswordCB'>cupsSetPasswordCB</a>(my_password_cb); | |
| 945 | </pre> | |
| 946 | ||
| 947 | <p>Similarly, a GUI could display the prompt string in a window with input | |
| 948 | fields for the username and password. The username should default to the | |
| 949 | string returned by the <a href="#cupsUser"><code>cupsUser</code></a> | |
