.TH ppd_emit_to_file 3 
.SH NAME
ppd_emit_to_file, ppd_emit_to_fd \- Output device specific code.
.SH SYNOPSIS
.nf
.B #include <ppd/ppd.h>
.sp
.BI "gboolean ppd_emit( PpdFile * " ppd ",FILE *" fp ",PpdSectionOrder " section " );"
.BI "gboolean ppd_emitfd( PpdFile * " ppd ", int " fd ",PpdSectionOrder " section " );"
.SH DESCRIPTION
The
.B 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:
.TP
.B PPD_ORDER_ANY
Option code can be anywhere in the file 
.TP
.B PPD_ORDER_DOCUMENT
Option code must be in the DocumentSetup section 
.TP
.B PPD_ORDER_EXIT
Option code must be sent prior to the document 
.TP
.B PPD_ORDER_JCL
Option code must be sent as a JCL command 
.TP
.B PPD_ORDER_PAGE
Option code must be in the PageSetup section 
.TP
.B PPD_ORDER_PROLOG
Option code must be in the Prolog section 
.PP
The sections
.B PPD_ORDER_DOCUMENT
and
.B PPD_ORDER_PAGE
will also output code from the
.B PPD_ORDER_ANY
section.
.sp
Once a code section has been emitted it is marked as such and will not be
emitted unless it is re-marked.
