All Implemented Interfaces:

Proxy

@Generated("io.github.jwharm.JavaGI")
public class MemVTable
extends ProxyInstance

A set of functions used to perform memory allocation. The same GMemVTable must be used for all allocations in the same program; a call to g_mem_set_vtable(), if it exists, should be prior to any use of GLib.

This functions related to this has been deprecated in 2.46, and no longer work.
