OptionArg

class OptionArg

The OptionArg enum values determine which type of extra argument the options expect to find. If an option expects an extra argument, it can be specified in several ways; with a short option: -x arg, with a long option: --name arg or combined in a single argument: --name=arg.

Fields

class OptionArg

CALLBACK: The option provides a callback (of type GOptionArgFunc) to parse the extra argument.

DOUBLE: The option takes a double argument. The argument can be formatted either for the user’s locale or for the “C” locale. Since 2.12

FILENAME: The option takes a filename as argument, which will be in the GLib filename encoding rather than UTF-8.

FILENAME_ARRAY: The option takes a filename as argument, multiple uses of the option are collected into an array of strings.

INT: The option takes an integer argument.

INT64: The option takes a 64-bit integer. Like INT but for larger numbers. The number can be in decimal base, or in hexadecimal (when prefixed with 0x, for example, 0xffffffff). Since 2.12

NONE: No extra argument. This is useful for simple flags or booleans.

STRING: The option takes a UTF-8 string argument.

STRING_ARRAY: The option takes a string argument, multiple uses of the option are collected into an array of strings.
