ppd_check_option_is_marked(3)

NAME
ppd_check_option_is_marked, ppd_mark_defaults, ppd_mark_option - a set of functions for determining the current status of PPD options and selecting them.

SYNOPSIS
#include <ppd.h>

gboolean ppd_check_option_is_marked (PpdFile *ppd, const char *keyword, const char *option);

gint ppd_mark_option(PpdFile *ppd, const char *option, const char *choice);

void ppd_mark_defaults (PpdFile *ppd);

DESCRIPTION
These three functions are used to query the marked status of an option in a PPD file as well as forcing an option to be selected.

  ppd_check_option_is_marked(PpdFile *ppd, const char *option, const char *choice);
ppd_check_option_is_marked() accepts three parameters as input. The first is the PpdFile pointer to a PPD file obtained by calling one of the ppd_load(3) functions. The second parameter is the option of the keyword name. The final input parameter is the actual choice name.

  ppd_mark_option(PpdFile *ppd, const char *option, const char *choice);
ppd_mark_option allows the programmer to manually select an option in a PPD file. The parameters are the a valid PpdFile pointer (see ppd_file_new(3)), the option name, and the choice name.

  void ppd_mark_defaults (PpdFile *ppd);
ppd_mark_defaults() resets all the default options in the PPD file specified by the PpdFile pointer (see ppd_file_new(3)).

RETURN VALUE

ppd_check_option_is_marked()
    FALSE if the option is not currently selected and TRUE is it marked

ppd_mark_option()
    Always returns 0. The only means of determining whether or not the function succeeded is to make a subsequent call to ppd_check_option_is_marked() on the same option.
