Expand description
The #GOptionArg 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
.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
None
No extra argument. This is useful for simple flags or booleans.
String
The option takes a UTF-8 string argument.
Int
The option takes an integer argument.
Callback
The option provides a callback (of type #GOptionArgFunc) to parse the extra argument.
Filename
The option takes a filename as argument, which will be in the GLib filename encoding rather than UTF-8.
StringArray
The option takes a string argument, multiple uses of the option are collected into an array of strings.
FilenameArray
The option takes a filename as argument, multiple uses of the option are collected into an array of strings.
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
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
