/**
 * gst_context_writable_structure:
 * @context: The #GstContext.
 *
 * Get a writable version of the structure.
 *
 * Returns: The structure of the context. The structure is still
 * owned by the context, which means that you should not free it and
 * that the pointer becomes invalid when you free the context.
 * This function checks if @context is writable.

 * Since: 1.2
