ppd_emit_to_fileSYNOPSIS
#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("%%%%BeginProlog); ppd_emit_to_file(ppd, stdout, PPD_ORDER_PROLOG); printf("%%%%EndProlog); /* Setup section */ printf("%%%%BeginSetup); ppd_emit_to_file(ppd, stdout, PPD_ORDER_DOCUMENT); printf("%%%%EndSetup); /* Main document begins */ for (...) { printf("%%%%Page: 1 1); /* Re-mark so that this is emitted on each page */ ppd_mark_option(ppd,"PageSize","A4"); printf("%%%%PageSetup); ppd_emit_to_file(ppd, stdout, PPD_ORDER_PAGE); printf("%%%%EndPageSetup); /* Page info goes here */ ... } /* Send ending JCL code */ fputs(ppd->jcl_end->str,stdout);
