gconstpointer g_variant_get_fixed_array ( GVariant* value, gsize* n_elements, gsize element_size )
Provides access to the serialized data for an array of fixed-sized items.
value must be an array with fixed-sized elements. Numeric types are
fixed-size, as are tuples containing only other fixed-sized types.
element_size must be the size of a single element in the array,
as given by the section on
[serialized data memory][gvariant-serialized-data-memory].
In particular, arrays of these fixed-sized types can be interpreted
as an array of the given C type, with
element_size set to the size
the appropriate type:
G_VARIANT_TYPE_INT16 (etc.): #gint16 (etc.)
G_VARIANT_TYPE_BOOLEAN: #guchar (not #gboolean!)
For example, if calling this function for an array of 32-bit integers,
you might say
sizeof(gint32). This value isn’t used except for the purpose
of a double-check that the form of the serialized data matches the caller’s expectation.
n_elements, which must be non-
NULL, is set equal to the number of
items in the array.
A pointer to the location to store the number of items.
|The argument will be set by the function.|
|The instance takes ownership of the data, and is responsible for freeing it.|
The size of each element.
