<%GLibOptionArg>
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
.
alias G_OPTION_ARG_CALLBACK
The option provides a callback (of type GOptionArgFunc) to parse the extra argument.
alias G_OPTION_ARG_FILENAME
The option takes a filename as argument, which will be in the GLib filename encoding rather than UTF-8.
alias G_OPTION_ARG_STRING_ARRAY
The option takes a string argument, multiple uses of the option are collected into an array of strings.
alias G_OPTION_ARG_FILENAME_ARRAY
The option takes a filename as argument, multiple uses of the option are collected into an array of strings.
