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()
