宏定义说明

ircalloc

#define ircalloc	(		size,
			number
	)		irzalloc((size) * (number))

Allocate a block of memory and zero it.

参数

size	size of each block to allocate
number	number of blocks to allocate

返回

pointer to allocated memory, or NULL

函数说明

irfree()

void irfree

(

void *

buf

)

Free a block of memory

参数

buf

irmalloc()

void * irmalloc

(

size_t

size

)

Allocate a block of memory from internal RAM

参数

size	size of the block to allocate

返回

pointer to allocated memory, or NULL

irmalloc_dup()

void * irmalloc_dup	(	const void *	orig,
		size_t	size
	)

Duplicate the contents of a block of memory into irmalloc.

参数

orig	pointer to memory to duplicate
size	size of the block to duplicate

返回

pointer to block contain

irmalloc_get_human_readable_stats()

char * irmalloc_get_human_readable_stats

(

void

)

Get some human readable statistics on the memory management state

返回

the irmalloc'ed memory buffer containing a NULL terminated ASCII string of the human readbale stats; this memory must be irfree'd by the calling code note The stats format is variable and is not guaranteed to be parsable.NULL is returned if no memory is irmallocable

irmalloc_get_machine_readable_stats()

void irmalloc_get_machine_readable_stats	(	uint32_t *	current_allocated,
		uint32_t *	total_free,
		uint32_t *	max_free,
		uint32_t *	num_allocs,
		uint32_t *	num_frees
	)

Get some macine readable statistics on the memory management state

参数

current_allocated	pointer to memory to hold current allocated size
total_free	pointer to memory to hold current free pool size
max_free	pointer to memory to hold maximum free block size
num_allocs	pointer to memory to hold accumulated number of mallocs
num_frees	pointer to memory to hold accumulated number of frees

irmalloc_init_default()

void irmalloc_init_default

(

void

)

Initialise the internal memory with the default pool passed in via the linker

irmalloc_new_pool()

void irmalloc_new_pool	(	unsigned char *	start,
		size_t	size
	)

Add an additional memory pool to allocate from; the irmalloc implementation is not obliged to use this memory

参数

start	is the start memory address of the new pool
size	is number of bytes in the new memory pool

irmalloc_panicking()

void * irmalloc_panicking

(

size_t

size

)

Allocate a block of memory from internal RAM or panic on failure

参数

size	size of the block to allocate

返回

pointer to allocated memory

irmemalign()

void * irmemalign	(	size_t	boundary,
		size_t	size
	)

irrealloc()

void * irrealloc	(	void *	buf,
		size_t	size
	)

Reallocate a block of memory

irrealloc_panicking()

void * irrealloc_panicking	(	void *	buf,
		size_t	size
	)

Reallocate a block of memory or panic on failure

irzalloc()

void * irzalloc

(

size_t

size

)

Allocate a block of memory and zero it.

参数

size	size of the block to allocate

返回

pointer to allocated memory, or NULL
