489<p>The CUPS API provides the convenience functions needed to support
490applications, filters, printer drivers, and backends that need to interface

493<h3><a name='CLIENTS_AND_SERVERS'>Clients and Servers</a></h3>
494
495<p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows
496clients (applications) to communicate with a server (the scheduler) to get a
497list of printers, send print jobs, and so forth. You identify which server
498you want to communicate with using a pointer to the opaque structure
499<code>http_t</code>. All of the examples in this document use the
500<code>CUPS_HTTP_DEFAULT</code> constant, referring to the default connection
501to the scheduler. The <a href='api-httpipp.html' target='_top'>HTTP and IPP
502APIs</a> document provides more information on server connections.</p>

594<h3><a name='OPTIONS'>Options</a></h3>
595
596<p>Options are stored in arrays of
597<a href='#cups_option_t'><code>cups_option_t</code></a> structures. Each
598option has a name (<code>name</code>) and value (<code>value</code>)
599associated with it. The <a href='#cups_dest_t'><code>cups_dest_t</code></a>
600<code>num_options</code> and <code>options</code> members contain the
601default options for a particular destination, along with several informational
602attributes about the destination as shown in <a href='#TABLE1'>Table 1</a>.
603The <a href='#cupsGetOption'><code>cupsGetOption</code></a> function gets
604the value for the named option. For example, the following code lists the
605available destinations and their human-readable descriptions:</p>
606
607<pre class='example'>
608#include &lt;cups/cups.h&gt;
609

622
623<a href='#cupsFreeDests'>cupsFreeDests</a>(num_dests, dests);
624</pre>
625
626<p>You can create your own option arrays using the
627<a href='#cupsAddOption'><code>cupsAddOption</code></a> function, which
628adds a single named option to an array:</p>
629
630<pre class='example'>
631#include &lt;cups/cups.h&gt;
632
633int num_options = 0;
634<a href='#cups_option_t'>cups_option_t</a> *options = NULL;

642/* This replaces the first option we added */
643num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "new value", num_options, &amp;options);
644</pre>
645
646<p>Use a <code>for</code> loop to copy the options from a destination:</p>
647
648<pre class='example'>
649#include &lt;cups/cups.h&gt;

658 num_options, &amp;options);

659</pre>
660
661<p>Use the <a href='#cupsFreeOptions'><code>cupsFreeOptions</code></a>

669
670<p>Print jobs are identified by a locally-unique job ID number from 1 to
6712<sup>31</sup>-1 and have options and one or more files for printing to a
672single destination. The <a href='#cupsPrintFile'><code>cupsPrintFile</code></a>
673function creates a new job with one file. The following code prints the CUPS
674test page file:</p>

5a738aea
MS
687</pre>
688
689<p>The <a href='#cupsPrintFiles'><code>cupsPrintFiles</code></a> function
690creates a job with multiple files. The files are provided in a
691<code>char *</code> array:</p>

704</pre>
705
706<p>Finally, the <a href='#cupsCreateJob'><code>cupsCreateJob</code></a>
707function creates a new job with no files in it. Files are added using the
708<a href='#cupsStartDocument'><code>cupsStartDocument</code></a>,
709<a href='api-httpipp.html#cupsWriteRequestData'><code>cupsWriteRequestData</code></a>,
710and <a href='#cupsFinishDocument'><code>cupsFinishDocument</code></a> functions.

751</pre>
752
753<p>Once you have created a job, you can monitor its status using the
754<a href='#cupsGetJobs'><code>cupsGetJobs</code></a> function, which returns
755an array of <a href='#cups_job_t'><code>cups_job_t</code></a> structures.
756Each contains the job ID (<code>id</code>), destination name
757(<code>dest</code>), title (<code>title</code>), and other information
758associated with the job. The job array is freed using the
759<a href='#cupsFreeJobs'><code>cupsFreeJobs</code></a> function. The following

822
823<p>To cancel a job, use the
824<a href='#cupsCancelJob'><code>cupsCancelJob</code></a> function with the
825job ID:</p>
826
568fa3fa 827<pre class='example'>

834</pre>
835
836<h3><a name='ERROR_HANDLING'>Error Handling</a></h3>
837
838<p>If any of the CUPS API printing functions returns an error, the reason for
839that error can be found by calling the
840<a href='#cupsLastError'><code>cupsLastError</code></a> and
841<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> functions.
842<a href='#cupsLastError'><code>cupsLastError</code></a> returns the last IPP
843error code
844(<a href='api-httpipp.html#ipp_status_t'><code>ipp_status_t</code></a>)
845that was encountered, while
846<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> returns
847a (localized) human-readable string that can be shown to the user. For example,
848if any of the job creation functions returns a job ID of 0, you can use
849<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> to show
850the reason why the job could not be created:</p>
851
852<pre class='example'>
853#include &lt;cups/cups.h&gt;
854
855int job_id;
856
857if (job_id == 0)
858 puts(cupsLastErrorString());
859</pre>
860
861<h3><a name='PASSWORDS_AND_AUTHENTICATION'>Passwords and Authentication</a></h3>
862
863<p>CUPS supports authentication of any request, including submission of print
864jobs. The default mechanism for getting the username and password is to use the
865login user and a password from the console.</p>
866
867<p>To support other types of applications, in particular Graphical User
868Interfaces ("GUIs"), the CUPS API provides functions to set the default
869username and to register a callback function that returns a password string.</p>
870
871<p>The <a href="#cupsSetPasswordCB"><code>cupsSetPasswordCB</code></a>
872function is used to set a password callback in your program. Only one
873function can be used at any time.</p>
874
875<p>The <a href="#cupsSetUser"><code>cupsSetUser</code></a> function sets the
876current username for authentication. This function can be called by your
877password callback function to change the current username as needed.</p>
878
879<p>The following example shows a simple password callback that gets a
880username and password from the user:</p>
881
882<pre class='example'>
883#include &lt;cups/cups.h&gt;
884
885const char *
886my_password_cb(const char *prompt)
887{
888 char user[65];
889
890
891 puts(prompt);
892
893 /* Get a username from the user */
894 printf("Username: ");
895 if (fgets(user, sizeof(user), stdin) == NULL)
896 return (NULL);
897
898 /* Strip the newline from the string and set the user */
899 user[strlen(user) - 1] = '\0';
900
901 <a href='#cupsSetUser'>cupsSetUser</a>(user);
902
903 /* Use getpass() to ask for the password... */
904 return (getpass("Password: "));
905}
906
907<a href='#cupsSetPasswordCB'>cupsSetPasswordCB</a>(my_password_cb);
908</pre>
909
910<p>Similarly, a GUI could display the prompt string in a window with input
911fields for the username and password. The username should default to the
912string returned by the <a href="#cupsUser"><code>cupsUser</code></a>
913function.</p>
