NAME
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 *keyword);
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.
RETURN VALUE
- ppd_find_choice()
- Return a pointer to an option choice; NULL in the case of a failure
- ppd_find_marked_choice()
- Return the marked choice for the specified option; NULL in the case of a failure
- ppd_find_option_by_keyword()
- Return a pointer to the specified option; NULL in the case of a failure
