NAME

       ppd_file_new_from_filep, ppd_file_new_from_fd, ppd_file_new - Parse a ppd file and load it into the ppd_file_t structure.

SYNOPSIS

       #include <ppd.h>

       ppd_file_t *ppd_file_new_from_filep(FILE* fp");"

       ppd_file_t *ppd_file_new_from_fd(int fd");"

       ppd_file_t *ppd_file_new(const char * filename");"

DESCRIPTION

       The ppd_file_new_from_filep function parses the specified PPD file.

RETURN VALUES

       Upon  successful  completion  ppd_file_new_from_filep,  ppd_file_new_from_fd , ppd_file_new return a ppd_file_t pointer. Otherwise, NULL is
       returned and errno is set.

       ENODEV the FILE pointer passed into ppd_file_new_from_filep or the file descriptor passed into ppd_file_new_from_fd is NULL.

       EBADF  the file doesn't appear to be a PPD file.

       ENOTTY no idea what these errors are. Probably PPD parse errors.

       Other errors can be returned in errno by a failure in fdopen or fopen.

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.
