 490 <h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
 491
 492 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
 493 Description ("PPD") files which are used for all printers with a driver. With
 494 it you can obtain the data necessary to display printer options to users, mark
 495 option choices and check for conflicting choices, and output marked choices in
 496 PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 497 structure contains all of the information in a PPD file.</p>
 498
 499 <blockquote><b>Note:</b>
 500
 501 <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
 502 terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
 503 features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
 504 values as case-insensitive strings, so option "InputSlot" and choice "Upper"
 505 are equivalent to "inputslot" and "upper", respectively.</p>
 506 </blockquote>
 507
 508 <h3><a name="LOADING">Loading a PPD File</a></h3>
 509
 510 <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
 511 PPD file and loads it into memory. For example, the following code opens the
 512 current printer's PPD file in a CUPS filter:</p>
 513
 514 <pre class="example">
 515 #include &lt;cups/ppd.h&gt;
 516
 517 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 518 </pre>
 519
 520 <p>The return value is a pointer to a new
 521 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
 522 if the PPD file does not exist or cannot be loaded. The
 523 <a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
 524 by the structure:</p>
 525
 526 <pre class="example">
 527 #include &lt;cups/ppd.h&gt;
 528
 529 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 530
 531 <a href="#ppdClose">ppdClose</a>(ppd);
 532 </pre>
 533
 534 <p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 535 structure and any data in it will no longer be valid.</p>
 536
 537 <h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
 538
 539 <p>PPD files support multiple options, which are stored in arrays of
 540 <a href="#ppd_option_t"><code>ppd_option_t</code></a> and
 541 <a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
 542
 543 <p>Each option in turn is associated with a group stored in a
 544 <a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
 545 specified in the PPD file; if an option is not associated with a group
 546 then it is put in an automatically-generated "General" group. Groups can also
 547 have sub-groups, however CUPS currently ignores sub-groups because of past
 548 abuses of this functionality.</p>
 549
 550 <p>Option choices are selected by marking them using one of three functions. The
 551 first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
 552 selects all of the default options in the PPD file:</p>
 553
 554 <pre class="example">
 555 #include &lt;cups/ppd.h&gt;
 556
 557 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 558
 559 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 560 </pre>
 561
 562 <p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
 563 which selects a single option choice in the PPD file. For example, the following
 564 code selects the upper paper tray:</p>
 565
 566 <pre class="example">
 567 #include &lt;cups/ppd.h&gt;
 568
 569 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 570
 571 <a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
 572 </pre>
 573
 574 <p>The last function is
 575 <a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
 576 multiple option choices in the PPD file from an array of CUPS options, mapping
 577 IPP attributes like "media" and "sides" to their corresponding PPD options. You
 578 typically use this function in a print filter with
 579 <code>cupsParseOptions</code> and
 580 <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
 581 the option choices needed for the job, for example:</p>
 582
 583 <pre class="example">
 584 #include &lt;cups/ppd.h&gt;
 585
 586 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 587 cups_option_t *options = NULL;
 588 int num_options = cupsParseOptions(argv[5], 0, &amp;options);
 589
 590 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 591 <a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
 592 cupsFreeOptions(num_options, options);
 593 </pre>
 594
 595 <h3><a name="CONSTRAINTS">Constraints</a></h3>
 596
 597 <p>PPD files support specification of conflict conditions, called
 598 constraints, between different options. Constraints are stored in an array of
 599 <a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
 600 the options and choices that conflict with each other. The
 601 <a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
 602 how many of the selected options are incompatible. Since constraints are
 603 normally specified in pairs, the returned value is typically an even number.</p>
 604
 605 <h3><a name="PAGE_SIZES">Page Sizes</a></h3>
 606
 607 <p>Page sizes are special options which have physical dimensions and margins
 608 associated with them. The size information is stored in
 609 <a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
 610 by looking up the named size with the
 611 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
 612 margins are returned in units called points; there are 72 points per inch. If
 613 you pass <code>NULL</code> for the size, the currently selected size is
 614 returned:</p>
 615
 616 <pre class="example">
 617 #include &lt;cups/ppd.h&gt;
 618
 619 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 620 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
 621 </pre>
 622
 623 <p>Besides the standard page sizes listed in a PPD file, some printers
 624 support variable or custom page sizes. Custom page sizes are supported if the
 625 <code>variables_sizes</code> member of the
 626 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
 627 The <code>custom_min</code>, <code>custom_max</code>, and
 628 <code>custom_margins</code> members of the
 629 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
 630 of the printable area. To get the resulting media size, use a page size string
 631 of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
 632 in points. Custom page size names can also be specified in inches
 633 ("Custom.<i>width</i>x<i>height</i>in"), centimeters
 634 ("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
 635 ("Custom.<i>width</i>x<i>height</i>mm"):</p>
 636
 637 <pre class="example">
 638 #include &lt;cups/ppd.h&gt;
 639
 640 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 641
 642 /* Get an 576x720 point custom page size */
 643 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
 644
 645 /* Get an 8x10 inch custom page size */
 646 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
 647
 648 /* Get a 100x200 millimeter custom page size */
 649 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
 650
 651 /* Get a 12.7x34.5 centimeter custom page size */
 652 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
 653 </pre>
 654
 655 <p>If the PPD does not support variable page sizes, the
 656 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
 657 <code>NULL</code>.</p>
 658
 659 <h3><a name="ATTRIBUTES">Attributes</a></h3>
 660
 661 <p>Every PPD file is composed of one or more attributes. Most of these
 662 attributes are used to define groups, options, choices, and page sizes,
 663 however several informational attributes may be present which you can access
 664 in your program or filter. Attributes normally look like one of the following
 665 examples in a PPD file:</p>
 666
 667 <pre class="example">
 668 *name: "value"
 669 *name spec: "value"
 670 *name spec/text: "value"
 671 </pre>
 672
 673 <p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
 674 <a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
 675 first and next instances, respectively, of the named attribute with the given
 676 "spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
 677 structure. If you provide a NULL specifier string, all attributes with the
 678 given name will be returned. For example, the following code lists all of the
 679 <code>Product</code> attributes in a PPD file:</p>
 680
 681 <pre class="example">
 682 #include &lt;cups/ppd.h&gt;
 683
 684 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 685 <a href="#ppd_attr_t">ppd_attr_t</a> *attr;
 686
 687 for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
 688      attr != NULL;
 689      attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
 690   puts(attr->value);
 691 </pre>

 740 <p class="description">1 on success, 0 on failure</p>
 741 <h4 class="discussion">Discussion</h4>
 742 <p class="discussion">This function attempts to resolve any conflicts in a marked PPD, returning
 743 a list of option changes that are required to resolve them.  On input,
 744 &quot;num_options&quot; and &quot;options&quot; contain any pending option changes that have
 745 not yet been marked, while &quot;option&quot; and &quot;choice&quot; contain the most recent
 746 selection which may or may not be in &quot;num_options&quot; or &quot;options&quot;.<br>
 747 <br>
 748 On successful return, &quot;num_options&quot; and &quot;options&quot; are updated to contain
 749 &quot;option&quot; and &quot;choice&quot; along with any changes required to resolve conflicts
 750 specified in the PPD file and 1 is returned.<br>
 751 <br>
 752 If option conflicts cannot be resolved, &quot;num_options&quot; and &quot;options&quot; are not
 753 changed and 0 is returned.<br>
 754 <br>
 755 When resolving conflicts, <code>cupsResolveConflicts</code> does not consider
 756 changes to the current page size (<code>media</code>, <code>PageSize</code>, and
 757 <code>PageRegion</code>) or to the most recent option specified in &quot;option&quot;.
 758 Thus, if the only way to resolve a conflict is to change the page size
 759 or the option the user most recently changed, <code>cupsResolveConflicts</code>
 760 will return 0 to indicate it was unable to resolve the conflicts.<br>
 761 <br>
 762 The <code>cupsResolveConflicts</code> function uses one of two sources of option
 763 constraint information.  The preferred constraint information is defined by
 764 <code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this
 765 case, the PPD file provides constraint resolution actions.<br>
 766 <br>
 767 The backup constraint information is defined by the
 768 <code>UIConstraints</code> and <code>NonUIConstraints</code> attributes.  These
 769 constraints are resolved algorithmically by first selecting the default
 770 choice for the conflicting option, then iterating over all possible choices
 771 until a non-conflicting option choice is found.
