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);
