403with the CUPS scheduler.</p>

407<p>Printers and classes (collections of printers) are accessed through
408the <a href="#cups_dest_t"><code>cups_dest_t</code></a> structure which
409includes the name (<code>name</code>), instance (<code>instance</code> -
410a way of selected certain saved options), and the options and attributes
411associated with that destination (<code>num_options</code> and
412<code>options</code>). Destinations are created using the
413<a href="#cupsGetDests"><code>cupsGetDests</code></a> function and freed
414using the <a href='#cupsFreeDests'><code>cupsFreeDests</code></a> function.
415The <a href='#cupsGetDest'><code>cupsGetDest</code></a> function finds a
416specific destination for printing:</p>

495<h3><a name='OPTIONS'>Options</a></h3>
496
497<p>Options are stored in arrays of
498<a href='#cups_option_t'><code>cups_option_t</code></a> structures. Each
499option has a name (<code>name</code>) and value (<code>value</code>)
500associated with it. The <a href='#cups_dest_t'><code>cups_dest_t</code></a>
501<code>num_options</code> and <code>options</code> members contain the
502default options for a particular destination, along with several informational
503attributes about the destination as shown in <a href='#TABLE1'>Table 1</a>.
504The <a href='#cupsGetOption'><code>cupsGetOption</code></a> function gets
505the value for the named option. For example, the following code lists the
506available destinations and their human-readable descriptions:</p>
507
508<pre class='example'>
509#include &lt;cups/cups.h&gt;
510

516
517for (i = num_dests, dest = dests; i > 0; i --, dest ++)
518 if (dest->instance == NULL)
519 {
520 value = <a href='#cupsGetOption'>cupsGetOption</a>("printer-info", dest->num_options, dest->options);
521 printf("%s (%s)\n", dest->name, value ? value : "no description");
522 }
523
524<a href='#cupsFreeDests'>cupsFreeDests</a>(num_dests, dests);
525</pre>
526
527<p>You can create your own option arrays using the
528<a href='#cupsAddOption'><code>cupsAddOption</code></a> function, which
529adds a single named option to an array:</p>
530
531<pre class='example'>
532#include &lt;cups/cups.h&gt;
533
534int num_options = 0;
535<a href='#cups_option_t'>cups_option_t</a> *options = NULL;
536
537/* The returned num_options value is updated as needed */
538num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "value", num_options, &amp;options);
539
540/* This adds a second option value */
541num_options = <a href='#cupsAddOption'>cupsAddOption</a>("second", "value", num_options, &amp;options);
542
543/* This replaces the first option we added */
544num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "new value", num_options, &amp;options);
545</pre>
546
547<p>Use a <code>for</code> loop to copy the options from a destination:</p>
548
549<pre class='example'>
550#include &lt;cups/cups.h&gt;
551
552int i;
553int num_options = 0;

559</pre>
560
561<p>Use the <a href='#cupsFreeOptions'><code>cupsFreeOptions</code></a>
562function to free the options array when you are done using it:</p>

568<h3><a name='PRINT_JOBS'>Print Jobs</a></h3>
569
570<p>Print jobs are identified by a locally-unique job ID number from 1 to
5712<sup>31</sup>-1 and have options and one or more files for printing to a
572single destination. The <a href='#cupsPrintFile'><code>cupsPrintFile</code></a>
573function creates a new job with one file. The following code prints the CUPS
574test page file:</p>
575
576<pre class='example'>

584/* Print a single file */
585job_id = <a href='#cupsPrintFile'>cupsPrintFile</a>(dest->name, "/usr/share/cups/data/testprint.ps", "Test Print", num_options, options);
586</pre>
587
588<p>The <a href='#cupsPrintFiles'><code>cupsPrintFiles</code></a> function
589creates a job with multiple files. The files are provided in a
590<code>char *</code> array:</p>
591
592<pre class='example'>

601/* Print three files */

603</pre>
604
605<p>Finally, the <a href='#cupsCreateJob'><code>cupsCreateJob</code></a>
606function creates a new job with no files in it. Files are added using the
607<a href='#cupsStartDocument'><code>cupsStartDocument</code></a>,
608<a href='api-httpipp.html#cupsWriteRequestData'><code>cupsWriteRequestData</code></a>,
609and <a href='#cupsFinishDocument'><code>cupsFinishDocument</code></a> functions.
610The following example creates a job with 10 text files for printing:</p>

647}
648</pre>
649
650<p>Once you have created a job, you can monitor its status using the
651<a href='#cupsGetJobs'><code>cupsGetJobs</code></a> function, which returns
652an array of <a href='#cups_job_t'><code>cups_job_t</code></a> structures.
653Each contains the job ID (<code>id</code>), destination name
654(<code>dest</code>), title (<code>title</code>), and other information
655associated with the job. The job array is freed using the
656<a href='#cupsFreeJobs'><code>cupsFreeJobs</code></a> function. The following
657example monitors a specific job ID, showing the current job state once every
6585 seconds until the job is completed:</p>

717}
718</pre>
719
720<p>To cancel a job, use the
721<a href='#cupsCancelJob'><code>cupsCancelJob</code></a> function with the
722job ID:</p>
723
724<pre class='exmaple'>
725#include &lt;cups/cups.h&gt;
726
727<a href='#cups_dest_t'>cups_dest_t</a> *dest;
728int job_id;
729
730<a href='#cupsCancelJob'>cupsCancelJob</a>(dest->name, job_id);
731</pre>
732
733<h3><a name='ERROR_HANDLING'>Error Handling</a></h3>
734
735<p>If any of the CUPS API printing functions returns an error, the reason for
736that error can be found by calling the
737<a href='#cupsLastError'><code>cupsLastError</code></a> and
738<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> functions.
739<a href='#cupsLastError'><code>cupsLastError</code></a> returns the last IPP
740error code
741(<a href='api-httpipp.html#ipp_status_t'><code>ipp_status_t</code></a>)
742that was encountered, while
743<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> returns
744a (localized) human-readable string that can be shown to the user. For example,
745if any of the job creation functions returns a job ID of 0, you can use
746<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> to show
747the reason why the job could not be created:</p>
748
749<pre class='example'>
750#include &lt;cups/cups.h&gt;
751
752int job_id;
753
754if (job_id == 0)
755 puts(cupsLastErrorString());
756</pre>
757
758<h3><a name='PASSWORDS_AND_AUTHENTICATION'>Passwords and Authentication</a></h3>
759
760<p>CUPS supports authentication of any request, including submission of print
761jobs. The default mechanism for getting the username and password is to use the
762login user and a password from the console.</p>
763
764<p>To support other types of applications, in particular Graphical User
765Interfaces ("GUIs"), the CUPS API provides functions to set the default
766username and to register a callback function that returns a password string.</p>
767
768<p>The <a href="#cupsSetPasswordCB"><code>cupsSetPasswordCB</code></a>
769function is used to set a password callback in your program. Only one
770function can be used at any time.</p>
771
772<p>The <a href="#cupsSetUser"><code>cupsSetUser</code></a> function sets the
773current username for authentication. This function can be called by your
774password callback function to change the current username as needed.</p>
775
776<p>The following example shows a simple password callback that gets a
777username and password from the user:</p>
778
779<pre class='example'>
780#include &lt;cups/cups.h&gt;
781
782const char *
783my_password_cb(const char *prompt)
784{
785 char user[65];
786
787
788 puts(prompt);
789
790 /* Get a username from the user */
791 printf("Username: ");
792 if (fgets(user, sizeof(user), stdin) == NULL)
793 return (NULL);
794
795 /* Strip the newline from the string and set the user */
796 user[strlen(user) - 1] = '\0';
797
798 <a href='#cupsSetUser'>cupsSetUser</a>(user);
799
800 /* Use getpass() to ask for the password... */
801 return (getpass("Password: "));
802}
803
804<a href='#cupsSetPasswordCB'>cupsSetPasswordCB</a>(my_password_cb);
805</pre>
806
807<p>Similarly, a GUI could display the prompt string in a window with input
808fields for the username and password. The username should default to the
809string returned by the <a href="#cupsUser"><code>cupsUser</code></a>
810function.</p>
