Referenced by getopt_long(), match_long_option(), print_usage(), and reparse_options().

◆ flag

int* option::flag

Location into which to store val, or NULL.

See the description for val for more details.

Definition at line 37 of file getopt.h.

Referenced by match_long_option().

◆ val

int option::val

Value to return.

If flag is NULL, then this is the value that will be returned by getopt_long() when this option is found, and should therefore be set to the equivalent short option character.

If flag is non-NULL, then this value will be written to the location pointed to by @flag, and getopt_long() will return 0.
