Macro Definition Documentation

◆ LWIP_MEMPOOL_ALLOC

#define LWIP_MEMPOOL_ALLOC ( name ) memp_malloc_pool(&memp_ ## name)

Allocate from a private memory pool

Definition at line 122 of file memp.h.

◆ LWIP_MEMPOOL_DECLARE

#define LWIP_MEMPOOL_DECLARE	(	name,
		num,
		size,
		desc
	)

Value:

LWIP_DECLARE_MEMORY_ALIGNED(memp_memory_ ## name ## _base, ((num) * (MEMP_SIZE + MEMP_ALIGN_SIZE(size)))); \
    \
  LWIP_MEMPOOL_DECLARE_STATS_INSTANCE(memp_stats_ ## name) \
    \
  static struct memp *memp_tab_ ## name; \
    \
  const struct memp_desc memp_ ## name = { \
    DECLARE_LWIP_MEMPOOL_DESC(desc) \
    LWIP_MEMPOOL_DECLARE_STATS_REFERENCE(memp_stats_ ## name) \
    LWIP_MEM_ALIGN_SIZE(size), \
    (num), \
    memp_memory_ ## name ## _base, \
    &memp_tab_ ## name \
  };

Declare a private memory pool Private mempools example: .h: only when pool is used in multiple .c files: LWIP_MEMPOOL_PROTOTYPE(my_private_pool); .c:

in global variables section: LWIP_MEMPOOL_DECLARE(my_private_pool, 10, sizeof(foo), "Some description")
call ONCE before using pool (e.g. in some init() function): LWIP_MEMPOOL_INIT(my_private_pool);
allocate: void* my_new_mem = LWIP_MEMPOOL_ALLOC(my_private_pool);
free: LWIP_MEMPOOL_FREE(my_private_pool, my_new_mem);

To relocate a pool, declare it as extern in cc.h. Example for GCC: extern u8_t attribute((section(".onchip_mem"))) memp_memory_my_private_pool[];

◆ LWIP_MEMPOOL_FREE

#define LWIP_MEMPOOL_FREE	(	name,
		x
	)	memp_free_pool(&memp_ ## name, (x))

Free element from a private memory pool

Definition at line 127 of file memp.h.

◆ LWIP_MEMPOOL_INIT

#define LWIP_MEMPOOL_INIT ( name ) memp_init_pool(&memp_ ## name)

Initialize a private memory pool

Definition at line 117 of file memp.h.

◆ LWIP_MEMPOOL_PROTOTYPE

#define LWIP_MEMPOOL_PROTOTYPE ( name ) extern const struct memp_desc memp_ ## name

Declare prototype for private memory pool if it is used in multiple files

Definition at line 67 of file memp.h.
