)

Description [src]

The type of function that can be called before and after parsing.

Parameters

context

Type: GOptionContext

The active GOptionContext.

The data is owned by the caller of the function.

group

Type: GOptionGroup

The group to which the function belongs.

The data is owned by the caller of the function.

data

Type: gpointer

User data added to the GOptionGroup containing the option when it was created with g_option_group_new().

The argument can be NULL.

The data is owned by the caller of the function.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the function completed successfully, FALSE if an error occurred, in which case error should be set with g_set_error().
