ppd_emit_to_file

ppd_emit_to_file(3)					     Library Functions Manual					       ppd_emit_to_file(3)

NAME

       ppd_emit_to_file, ppd_emit_to_fd - Output device specific code.

SYNOPSIS

       #include <ppd/ppd.h>

       gboolean ppd_emit( PpdFile * ppd,FILE *fp,PpdSectionOrder section );
       gboolean ppd_emitfd( PpdFile * ppd, int fd,PpdSectionOrder section );

DESCRIPTION

       The  ppd_emit_*	functions  output  the	device	specific code appropriate to the specified section that has not already been emitted.. The
       PpdFile pointer is obtained from opening a PPD file via the ppd_load(3) family of functions.  The section can be any one of the following:

       PPD_ORDER_ANY
	      Option code can be anywhere in the file

       PPD_ORDER_DOCUMENT
	      Option code must be in the DocumentSetup section

       PPD_ORDER_EXIT
	      Option code must be sent prior to the document

       PPD_ORDER_JCL
	      Option code must be sent as a JCL command

       PPD_ORDER_PAGE
	      Option code must be in the PageSetup section

       PPD_ORDER_PROLOG
	      Option code must be in the Prolog section

       The sections PPD_ORDER_DOCUMENT and PPD_ORDER_PAGE will also output code from the PPD_ORDER_ANY section.

       Once a code section has been emitted it is marked as such and will not be emitted unless it is re-marked.

EXAMPLE

	    /* Setup code to emitted */
	       ppd_mark_defaults(ppd);
	       ppd_mark_option(ppd,"Duplex","DuplexNoTumble");
	       ppd_mark_option(ppd,"PageSize","A4");

	    /* Emit initial code (including any reset and JCL code) */
	       ppd_emit_to_file(ppd,stdout,PPD_ORDER_EXIT);
	       fputs(ppd->jcl_begin->str,stdout);
	       ppd_emit_to_file(ppd, stdout, PPD_ORDER_JCL);
	       fputs(ppd->jcl_ps->str, stdout);

	    /* Any header comments go here */
	    ...

	    /* Prolog section */
	       printf("%%%%BeginProlog0);
	       ppd_emit_to_file(ppd, stdout, PPD_ORDER_PROLOG);
	       printf("%%%%EndProlog0);

	    /* Setup section */
	       printf("%%%%BeginSetup0);
	       ppd_emit_to_file(ppd, stdout, PPD_ORDER_DOCUMENT);
	       printf("%%%%EndSetup0);

	    /* Main document begins */
	    for (...) {
		 printf("%%%%Page: 1 10);

		 /* Re-mark so that this is emitted on each page */
		 ppd_mark_option(ppd,"PageSize","A4");
		 printf("%%%%PageSetup0);
		 ppd_emit_to_file(ppd, stdout, PPD_ORDER_PAGE);
		 printf("%%%%EndPageSetup0);

		 /* Page info goes here */
		 ...
	    }

	    /* Send ending JCL code */
	       fputs(ppd->jcl_end->str,stdout);
