479 | <h2 class='title'><a name='OVERVIEW'>Overview</a></h2> |
480 | ||
481 | <p>The CUPS API provides the convenience functions needed to support | |
482 | applications, filters, printer drivers, and backends that need to interface | |
483 | with the CUPS scheduler.</p> | |

485 | <h3><a name='CLIENTS_AND_SERVERS'>Clients and Servers</a></h3> |
486 | ||
487 | <p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows | |
488 | clients (applications) to communicate with a server (the scheduler) to get a | |
489 | list of printers, send print jobs, and so forth. You identify which server | |
490 | you want to communicate with using a pointer to the opaque structure | |
491 | <code>http_t</code>. All of the examples in this document use the | |
492 | <code>CUPS_HTTP_DEFAULT</code> constant, referring to the default connection | |
493 | to the scheduler. The <a href='api-httpipp.html' target='_top'>HTTP and IPP | |
494 | APIs</a> document provides more information on server connections.</p> | |

498 | <p>Printers and classes (collections of printers) are accessed through |
499 | the <a href="#cups_dest_t"><code>cups_dest_t</code></a> structure which | |
500 | includes the name (<code>name</code>), instance (<code>instance</code> - | |
568fa3fa MS |
501 | a way of selecting certain saved options/settings), and the options and |
502 | attributes associated with that destination (<code>num_options</code> and | |
5a738aea MS |
503 | <code>options</code>). Destinations are created using the |
504 | <a href="#cupsGetDests"><code>cupsGetDests</code></a> function and freed | |
505 | using the <a href='#cupsFreeDests'><code>cupsFreeDests</code></a> function. | |
506 | The <a href='#cupsGetDest'><code>cupsGetDest</code></a> function finds a | |
507 | specific destination for printing:</p> | |

5a738aea MS |
521 | <p>Passing <code>NULL</code> to |
522 | <a href='#cupsGetDest'><code>cupsGetDest</code></a> for the destination name | |
523 | will return the default destination. Similarly, passing a <code>NULL</code> | |
524 | instance will return the default instance for that destination.</p> | |

586 | <h3><a name='OPTIONS'>Options</a></h3> | |
587 | ||
588 | <p>Options are stored in arrays of | |
589 | <a href='#cups_option_t'><code>cups_option_t</code></a> structures. Each | |
590 | option has a name (<code>name</code>) and value (<code>value</code>) | |
591 | associated with it. The <a href='#cups_dest_t'><code>cups_dest_t</code></a> | |
592 | <code>num_options</code> and <code>options</code> members contain the | |
593 | default options for a particular destination, along with several informational | |
594 | attributes about the destination as shown in <a href='#TABLE1'>Table 1</a>. | |
595 | The <a href='#cupsGetOption'><code>cupsGetOption</code></a> function gets | |
596 | the value for the named option. For example, the following code lists the | |
597 | available destinations and their human-readable descriptions:</p> | |
598 | ||
599 | <pre class='example'> | |
600 | #include <cups/cups.h> | |

605 | int i; | |
606 | const char *value; | |
607 | ||
608 | for (i = num_dests, dest = dests; i > 0; i --, dest ++) | |
609 | if (dest->instance == NULL) | |

614 | ||
615 | <a href='#cupsFreeDests'>cupsFreeDests</a>(num_dests, dests); | |
616 | </pre> | |
617 | ||
618 | <p>You can create your own option arrays using the | |
619 | <a href='#cupsAddOption'><code>cupsAddOption</code></a> function, which | |
620 | adds a single named option to an array:</p> | |
621 | ||
622 | <pre class='example'> | |
623 | #include <cups/cups.h> | |
624 | ||
625 | int num_options = 0; | |
626 | <a href='#cups_option_t'>cups_option_t</a> *options = NULL; | |
627 | ||
628 | /* The returned num_options value is updated as needed */ | |
629 | num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "value", num_options, &options); | |
630 | ||
631 | /* This adds a second option value */ | |
632 | num_options = <a href='#cupsAddOption'>cupsAddOption</a>("second", "value", num_options, &options); | |
633 | ||
634 | /* This replaces the first option we added */ | |
635 | num_options = <a href='#cupsAddOption'>cupsAddOption</a>("first", "new value", num_options, &options); | |
636 | </pre> | |
637 | ||
638 | <p>Use a <code>for</code> loop to copy the options from a destination:</p> | |
639 | ||
640 | <pre class='example'> | |
641 | #include <cups/cups.h> | |
642 | ||
643 | int i; | |
644 | int num_options = 0; | |
645 | <a href='#cups_option_t'>cups_option_t</a> *options = NULL; | |
646 | <a href='#cups_dest_t'>cups_dest_t</a> *dest; | |
647 | ||
648 | for (i = 0; i < dest->num_options; i ++) | |
568fa3fa MS |
649 | num_options = <a href='#cupsAddOption'>cupsAddOption</a>(dest->options[i].name, dest->options[i].value, |
650 | num_options, &options); | |
5a738aea MS |
651 | </pre> |
652 | ||
653 | <p>Use the <a href='#cupsFreeOptions'><code>cupsFreeOptions</code></a> | |
654 | function to free the options array when you are done using it:</p> | |
655 | ||
656 | <pre class='example'> | |
657 | <a href='#cupsFreeOptions'>cupsFreeOptions</a>(num_options, options); | |
658 | </pre> | |
659 | ||
660 | <h3><a name='PRINT_JOBS'>Print Jobs</a></h3> | |
661 | ||
662 | <p>Print jobs are identified by a locally-unique job ID number from 1 to | |
663 | 2<sup>31</sup>-1 and have options and one or more files for printing to a | |
664 | single destination. The <a href='#cupsPrintFile'><code>cupsPrintFile</code></a> | |
665 | function creates a new job with one file. The following code prints the CUPS | |
666 | test page file:</p> | |
667 | ||
668 | <pre class='example'> | |
669 | #include <cups/cups.h> | |
670 | ||
671 | <a href='#cups_dest_t'>cups_dest_t</a> *dest; | |
672 | int num_options; | |
673 | <a href='#cups_option_t'>cups_option_t</a> *options; | |
674 | int job_id; | |
675 | ||

677 | job_id = <a href='#cupsPrintFile'>cupsPrintFile</a>(dest->name, "/usr/share/cups/data/testprint.ps", |
678 | "Test Print", num_options, options); | |
5a738aea MS |
679 | </pre> |
680 | ||
681 | <p>The <a href='#cupsPrintFiles'><code>cupsPrintFiles</code></a> function | |
682 | creates a job with multiple files. The files are provided in a | |
683 | <code>char *</code> array:</p> | |
684 | ||
685 | <pre class='example'> | |
686 | #include <cups/cups.h> | |
687 | ||
688 | <a href='#cups_dest_t'>cups_dest_t</a> *dest; | |
689 | int num_options; | |
690 | <a href='#cups_option_t'>cups_option_t</a> *options; | |
691 | int job_id; | |
692 | char *files[3] = { "file1.pdf", "file2.pdf", "file3.pdf" }; | |
693 | ||
694 | /* Print three files */ | |
695 | job_id = <a href='#cupsPrintFiles'>cupsPrintFiles</a>(dest->name, 3, files, "Test Print", num_options, options); | |
696 | </pre> | |
697 | ||
698 | <p>Finally, the <a href='#cupsCreateJob'><code>cupsCreateJob</code></a> | |
699 | function creates a new job with no files in it. Files are added using the | |
700 | <a href='#cupsStartDocument'><code>cupsStartDocument</code></a>, | |
701 | <a href='api-httpipp.html#cupsWriteRequestData'><code>cupsWriteRequestData</code></a>, | |
702 | and <a href='#cupsFinishDocument'><code>cupsFinishDocument</code></a> functions. | |
703 | The following example creates a job with 10 text files for printing:</p> | |
704 | ||
705 | <pre class='example'> | |
706 | #include <cups/cups.h> | |
707 | ||
708 | <a href='#cups_dest_t'>cups_dest_t</a> *dest; | |

741 | } | |
742 | } | |
743 | </pre> | |
744 | ||
745 | <p>Once you have created a job, you can monitor its status using the | |
746 | <a href='#cupsGetJobs'><code>cupsGetJobs</code></a> function, which returns | |
747 | an array of <a href='#cups_job_t'><code>cups_job_t</code></a> structures. | |
748 | Each contains the job ID (<code>id</code>), destination name | |
749 | (<code>dest</code>), title (<code>title</code>), and other information | |
750 | associated with the job. The job array is freed using the | |
751 | <a href='#cupsFreeJobs'><code>cupsFreeJobs</code></a> function. The following | |
752 | example monitors a specific job ID, showing the current job state once every | |
753 | 5 seconds until the job is completed:</p> | |

838 | <a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> returns | |
839 | a (localized) human-readable string that can be shown to the user. For example, | |
840 | if any of the job creation functions returns a job ID of 0, you can use | |
841 | <a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> to show | |
842 | the reason why the job could not be created:</p> | |
843 | ||
844 | <pre class='example'> | |
845 | #include <cups/cups.h> | |
846 | ||
847 | int job_id; | |
848 | ||
849 | if (job_id == 0) | |
850 | puts(cupsLastErrorString()); | |

853 | <h3><a name='PASSWORDS_AND_AUTHENTICATION'>Passwords and Authentication</a></h3> | |
854 | ||
855 | <p>CUPS supports authentication of any request, including submission of print | |
856 | jobs. The default mechanism for getting the username and password is to use the | |
857 | login user and a password from the console.</p> | |
858 | ||
859 | <p>To support other types of applications, in particular Graphical User | |
860 | Interfaces ("GUIs"), the CUPS API provides functions to set the default | |
861 | username and to register a callback function that returns a password string.</p> | |
862 | ||
863 | <p>The <a href="#cupsSetPasswordCB"><code>cupsSetPasswordCB</code></a> | |
864 | function is used to set a password callback in your program. Only one | |
865 | function can be used at any time.</p> | |
866 | ||
867 | <p>The <a href="#cupsSetUser"><code>cupsSetUser</code></a> function sets the | |
868 | current username for authentication. This function can be called by your | |
869 | password callback function to change the current username as needed.</p> | |
870 | ||
871 | <p>The following example shows a simple password callback that gets a | |
872 | username and password from the user:</p> | |
873 | ||
874 | <pre class='example'> | |
875 | #include <cups/cups.h> | |
876 | ||
877 | const char * | |
878 | my_password_cb(const char *prompt) | |
879 | { | |
880 | char user[65]; | |
881 | ||
882 | ||
883 | puts(prompt); | |
884 | ||
885 | /* Get a username from the user */ | |
886 | printf("Username: "); | |
887 | if (fgets(user, sizeof(user), stdin) == NULL) | |
888 | return (NULL); | |
889 | ||
890 | /* Strip the newline from the string and set the user */ | |
891 | user[strlen(user) - 1] = '\0'; | |
892 | ||
893 | <a href='#cupsSetUser'>cupsSetUser</a>(user); | |
894 | ||
895 | /* Use getpass() to ask for the password... */ | |
896 | return (getpass("Password: ")); | |
897 | } | |
898 | ||
899 | <a href='#cupsSetPasswordCB'>cupsSetPasswordCB</a>(my_password_cb); | |
900 | </pre> | |
901 | ||
902 | <p>Similarly, a GUI could display the prompt string in a window with input | |
903 | fields for the username and password. The username should default to the | |
904 | string returned by the <a href="#cupsUser"><code>cupsUser</code></a> | |
905 | function.</p> | |
