Detailed Description

Memory pool API

lwIP internal memory pools (do not use in application code) This file is deliberately included multiple times: once with empty definition of LWIP_MEMPOOL() to handle all includes and multiple times to build up various lists of mem pools.

Enumeration Type Documentation

◆ memp_t

enum memp_t

Create the list of all memory pools managed by memp. MEMP_MAX represents a NULL pool at the end

Function Documentation

◆ memp_free()

void memp_free	(	memp_t	type,
		void *	mem
	)

Put an element back into its pool.

Parameters

type	the pool where to put mem
mem	the memp element to free

◆ memp_init()

void memp_init ( void )

Initializes lwIP built-in pools. Related functions: memp_malloc, memp_free

Carves out memp_memory into linked lists for each pool-type.

◆ memp_malloc()

void* memp_malloc ( memp_t type )

Get an element from a specific pool.
