ppd_find_choice(3)					     Library Functions Manual						ppd_find_choice(3)

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
