ppd_check_option_is_marked(3)               DragonFly Library Functions Manual


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.
