int* gk_option::flag

See the discussion on gk_option::val

Definition at line 34 of file gk_getopt.h.

int gk_option::has_arg

This field says whether the option takes an argument. It is an integer, and there are three legitimate values: no_argument, required_argument and optional_argument.

Definition at line 30 of file gk_getopt.h.

char* gk_option::name

This field is the name of the option.

Definition at line 29 of file gk_getopt.h.

int gk_option::val

These fields control how to report or act on the option when it occurs.

If flag is a null pointer, then the val is a value which identifies this option. Often these values are chosen to uniquely identify particular long options.

If flag is not a null pointer, it should be the address of an int variable which is the flag for this option. The value in val is the value to store in the flag to indicate that the option was seen.
