If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it: (1) one is to pass a pointer-to-pointer parameter, like: int my_malloc(int size, char **pmem) { *pmem=(char *)malloc(size); if(*pmem==NULL)... (11 Replies)

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); SEE ALSO
