Check a ppd file for conflicts
int ppd_get_num_conflicts (PpdFile *ppd);
The ppd_get_num_conflicts() function is used to determine the number of option conflicts within a given PPD file. The input to ppd_get_num_conflicts is a pointer to a PpdFile structure which is obtained by one of the ppd_file_new(3) functions.
The integer returned from the functions is the number of option conflicts located in the PPD file. Note that if the input parameter is a NULL pointer, the function will return 0.
