ppd_find_choice, ppd_find_marked_choice, ppd_find_option_by_keyword -
set of functions for returning pointers to choices from PPD files.
SYNOPSIS
#include <ppd.h>
PpdChoice *ppd_find_choice (PpdOption *o, const char *choice);
PpdChoice *ppd_find_marked_choice (PpdFile *ppd, const char *keyword);
PpdOption *ppd_find_option_by_keyword (PpdFile *ppd, const char *key‐
word);
DESCRIPTION
These three functions allow the programmer access options and choices
within a PPD file.
PpdChoice *ppd_find_choice (PpdOption *o, const char *choice);
This function accepts two parameters. The first is a pointer to a PPD
option structure and the second is the name of the choice to locate.
PpdChoice *ppd_find_marked_choice (PpdFile *ppd, const char *keyword);
This function accepts a valid PpdFile pointer (see ppd_file_new(3)) and
a keyword or option name to locate in the PPD file.
PpdOption *ppd_find_option_by_keyword (PpdFile *ppd, const char *keyword);
This function accepts two parameters which are identical to those used
when invoking the ppd_find_marked_choice() function. However, the
ppd_find_option_by_keyword() function does not mark the designated
option as being selected.
