663 | <h2 class='title'><a name='OVERVIEW'>Overview</a></h2> |
| 664 | ||
| 665 | <p>The CUPS HTTP and IPP APIs provide low-level access to the HTTP and IPP | |
| 666 | protocols and CUPS scheduler. They are typically used by monitoring and | |
| 667 | administration programs to perform specific functions not supported by the | |
| 668 | high-level CUPS API functions.</p> | |
| 669 | ||
| 670 | <p>The HTTP APIs use an opaque structure called | |
| 671 | <a href='#http_t'><code>http_t</code></a> to manage connections to | |
| 672 | a particular HTTP or IPP server. The | |
| 673 | <a href='#httpConnectEncrypt'><code>httpConnectEncrypt</code></a> function is | |
| 674 | used to create an instance of this structure for a particular server. | |
| 675 | The constant <code>CUPS_HTTP_DEFAULT</code> can be used with all of the | |
| 676 | <code>cups</code> functions to refer to the default CUPS server - the functions | |
| 677 | create a per-thread <a href='#http_t'><code>http_t</code></a> as needed.</p> | |
| 678 | ||
| 82cc1f9a MS |
679 | <p>The IPP APIs use two opaque structures for requests (messages sent to the CUPS scheduler) and responses (messages sent back to your application from the scheduler). The <a href='#ipp_t'><code>ipp_t</code></a> type holds a complete request or response and is allocated using the <a href='#ippNew'><code>ippNew</code></a> or <a href='#ippNewRequest'><code>ippNewRequest</code></a> functions and freed using the <a href='#ippDelete'><code>ippDelete</code></a> function.</p> |
| 680 | ||
| 681 | <p>The second opaque structure is called <a href='#ipp_attribute_t'><code>ipp_attribute_t</code></a> and holds a single IPP attribute which consists of a group tag (<a href='#ippGetGroupTag'><code>ippGetGroupTag</code></a>), a value type tag (<a href='#ippGetValueTag'><code>ippGetValueTag</code></a>), the attribute name (<a href='#ippGetName'><code>ippGetName</code></a>), and 1 or more values (<a href='#ippGetCount'><code>ippGetCount</code></a>, <a href='#ippGetBoolean'><code>ippGetBoolean</code></a>, <a href='#ippGetCollection'><code>ippGetCollection</code></a>, <a href='#ippGetDate'><code>ippGetDate</code></a>, <a href='#ippGetInteger'><code>ippGetInteger</code></a>, <a href='#ippGetRange'><code>ippGetRange</code></a>, <a href='#ippGetResolution'><code>ippGetResolution</code></a>, and <a href='#ippGetString'><code>ippGetString</code></a>). Attributes are added to an <a href='#ipp_t'><code>ipp_t</code></a> pointer using one of the <code>ippAdd</code> functions. For example, use <a href='#ippAddString'><code>ippAddString</code></a> to add the "printer-uri" and "requesting-user-name" string attributes to a request:</p> | |
| 5a738aea MS |
682 | |
| 683 | <pre class='example'> | |
| 684 | <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); | |
| 685 | ||
| 82cc1f9a MS |
686 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", |
| 687 | NULL, "ipp://localhost/printers/"); | |
| 5a738aea MS |
688 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", |
| 689 | NULL, cupsUser()); | |
| 690 | </pre> | |
| ef416fc2 | 691 | |
| 82cc1f9a | 692 | <p>Once you have created an IPP request, use the <code>cups</code> functions to send the request to and read the response from the server. For example, the <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function can be used for simple query operations that do not involve files:</p> |
| ef416fc2 | 693 | |
| 5a738aea MS |
694 | <pre class='example'> |
| 695 | #include <cups/cups.h> | |
| ef416fc2 | 696 | |
| ef416fc2 | 697 | |
| 5a738aea MS |
698 | <a href='#ipp_t'>ipp_t</a> *<a name='get_jobs'>get_jobs</a>(void) |
| 699 | { | |
| 700 | <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); | |
| ef416fc2 | 701 | |
| 82cc1f9a MS |
702 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", |
| 703 | NULL, "ipp://localhost/printers/"); | |
| 5a738aea MS |
704 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", |
| 705 | NULL, cupsUser()); | |
| 706 | ||
| 707 | return (<a href='#cupsDoRequest'>cupsDoRequest</a>(CUPS_HTTP_DEFAULT, request, "/")); | |
| 708 | } | |
| ef416fc2 | 709 | </pre> |
| 710 | ||
| 82cc1f9a | 711 | <p>The <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function frees the request and returns an IPP response or <code>NULL</code> pointer if the request could not be sent to the server. Once you have a response from the server, you can either use the <a href='#ippFindAttribute'><code>ippFindAttribute</code></a> and <a href='#ippFindNextAttribute'><code>ippFindNextAttribute</code></a> functions to find specific attributes, for example:</p> |
| ef416fc2 | 712 | |
| 5a738aea MS |
713 | <pre class='example'> |
| 714 | <a href='#ipp_t'>ipp_t</a> *response; | |
| 715 | <a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; | |
| bc44d920 | 716 | |
| 5a738aea MS |
717 | attr = <a href='#ippFindAttribute'>ippFindAttribute</a>(response, "printer-state", IPP_TAG_ENUM); |
| 718 | </pre> | |
| 719 | ||
| 82cc1f9a | 720 | <p>You can also walk the list of attributes with a simple <code>for</code> loop like this:</p> |
| 5a738aea MS |
721 | |
| 722 | <pre class='example'> | |
| 723 | <a href='#ipp_t'>ipp_t</a> *response; | |
| 724 | <a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; | |
| 725 | ||
| 82cc1f9a MS |
726 | for (attr = <a href='#ippFirstAttribute'>ippFirstAttribute</a>(response); attr != NULL; attr = <a href='#ippNextAttribute'>ippNextAttribute</a>(response)) |
| 727 | if (ippGetName(attr) == NULL) | |
| 5a738aea MS |
728 | puts("--SEPARATOR--"); |
| 729 | else | |
| 82cc1f9a | 730 | puts(ippGetName(attr)); |
| 5a738aea MS |
731 | </pre> |
| 732 | ||
| 82cc1f9a | 733 | <p>The <code>for</code> loop approach is normally used when collecting attributes for multiple objects (jobs, printers, etc.) in a response. Attributes with <code>NULL</code> names indicate a separator between the attributes of each object. For example, the following code will list the jobs returned from our previous <a href='#get_jobs'><code>get_jobs</code></a> example code:</p> |
| 5a738aea MS |
734 | |
| 735 | <pre class='example'> | |

| 794 | ||
| 795 | <p>To ensure proper encoding, the | |
| 796 | <a href='#httpAssembleURIf'><code>httpAssembleURIf</code></a> function must be | |
| 797 | used to format a "printer-uri" string for all printer-based requests:</p> | |

| 812 | <a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> functions are | |
| 813 | used for requests involving files. The | |
| 814 | <a href='#cupsDoFileRequest'><code>cupsDoFileRequest</code></a> function | |
| 815 | attaches the named file to a request and is typically used when sending a print | |
| 816 | file or changing a printer's PPD file:</p> | |

| 840 | ||
| 841 | <p>The <a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> function | |
| 842 | optionally attaches a file to the request and optionally saves a file in the | |
| 843 | response from the server. It is used when using a pipe for the request | |
| 844 | attachment or when using a request that returns a file, currently only | |
| 845 | <code>CUPS_GET_DOCUMENT</code> and <code>CUPS_GET_PPD</code>. For example, | |
| 846 | the following code will download the PPD file for the sample HP LaserJet | |
| 847 | printer driver:</p> | |
| 848 | ||
| 849 | <pre class='example'> | |
| 850 | char tempfile[1024]; | |

| 861 | </pre> | |
| 862 | ||
| 863 | <p>The example passes <code>-1</code> for the input file descriptor to specify | |
| 864 | that no file is to be attached to the request. The PPD file attached to the | |
| 865 | response is written to the temporary file descriptor we created using the | |
| 866 | <code>cupsTempFd</code> function.</p> | |
| 867 | ||
| 868 | <h3><a name='ASYNCHRONOUS_REQUEST_PROCESSING'>Asynchronous Request Processing</a></h3> | |
| 869 | ||
| 870 | <p>The <a href='#cupsSendRequest'><code>cupsSendRequest</code></a> and | |
| 871 | <a href='#cupsGetResponse'><code>cupsGetResponse</code></a> support | |
| 872 | asynchronous communications with the server. Unlike the other request | |
| 873 | functions, the IPP request is not automatically freed, so remember to | |
| 874 | free your request with the <a href='#ippDelete'><code>ippDelete</code></a> | |
| 875 | function.</p> | |
| 876 | ||
| 877 | <p>File data is attached to the request using the | |
| 878 | <a href='#cupsWriteRequestData'><code>cupsWriteRequestData</code></a> | |
| 879 | function, while file data returned from the server is read using the | |
| 880 | <a href='#cupsReadResponseData'><code>cupsReadResponseData</code></a> | |
| 881 | function. We can rewrite the previous <code>CUPS_GET_PPD</code> example | |
