#include <types.h>

Data Fields
void *	user
	Opaque pointer passed as the first argument of both callbacks.
void *(*	allocate )(void *user, size_t size)
	Returns a block of at least size bytes, aligned for any object type, or null on failure.
void(*	release )(void *user, void *memory)
	Releases a block returned by allocate.

Detailed Description

Memory management callbacks that replace malloc() and free(), for example with a pool or a bump allocator.

A header calls them when it is created. A handle calls them for all of its memory, and only when it is created and when a file is created or opened. Reading and writing allocate nothing, so a pool can be sized in advance.

The structure is frozen for the major version: it has these three fields and a new property of an allocator is a new function.

Examples

custom_allocator.c.
