typedef int(* ak_seg_cbk)(const void *p, size_t sz)

Gets a pointer to a memory segment and its size.

Parameters

p;	Pointer to segment memory.
sz;	Number of bytes in the segment.

Returns: 0 to stop iteration, non-zero to continue.

Definition at line 62 of file malloc.h.

Function Documentation

void* ak_aligned_alloc	(	size_t	aln,
		size_t	sz
	)

Attempt to allocate memory containing at least n bytes at an address which is a multiple of aln. aln must be a power of two. sz must be a multiple of aln.

Parameters

aln;	The alignment
sz;	The size for the allocation

Returns: 0 on failure, else pointer to at least n bytes of memory at an aligned address.

Definition at line 3024 of file malloc.c.

void* ak_calloc	(	size_t	n,
		size_t	s
	)

Attempt to allocate zeroed memory, containing at least n x s bytes.

Parameters

n;	Number of objects to zero.
s;	The size for each object.

Returns: 0 on failure, else pointer to at least s bytes of memory.

Definition at line 3011 of file malloc.c.

void ak_free ( void * p )

Return memory to the allocator.

Parameters

p;	Pointer to the memory to return.

Definition at line 3018 of file malloc.c.

void* ak_malloc ( size_t n )

Attempt to allocate memory containing at least n bytes.

Parameters

n;	The size for the allocation

Returns: 0 on failure, else pointer to at least n bytes of memory.

Definition at line 3005 of file malloc.c.

void ak_malloc_for_each_segment ( ak_seg_cbk cbk )

Iterate over all memory segments allocated.

Parameters

cbk;	Callback that is given the address of a segment and its size.

See also: ak_seg_cbk.

Definition at line 3059 of file malloc.c.

size_t ak_malloc_usable_size ( const void * p )

Return the usable size of the memory region pointed to by p.

Parameters

p;	Pointer to the memory to determize size of.

Returns: The number of bytes that can be written to in the region.

Definition at line 3042 of file malloc.c.

void* ak_memalign	(	size_t	aln,
		size_t	sz
	)

Attempt to allocate memory containing at least n bytes at an address which is a multiple of aln. aln must be a power of two.

Parameters

aln;	The alignment
sz;	The size for the allocation

Returns: 0 on failure, else pointer to at least n bytes of memory at an aligned address.

Definition at line 3036 of file malloc.c.

int ak_posix_memalign	(	void **	pptr,
		size_t	aln,
		size_t	sz
	)

Attempt to allocate memory containing at least n bytes at an address which is a multiple of aln and assign the address to *pptr. aln must be a power of two and a multiple of sizeof(void*).

Parameters

pptr;	The address where the memory address should be writted.
aln;	The alignment
sz;	The size for the allocation

Returns: 0 on success, 12 if no more memory is available, and 22 if aln was not a power of two and a multiple of sizeof(void*)

Definition at line 3030 of file malloc.c.

void* ak_realloc	(	void *	p,
		size_t	newsz
	)

Attempt to grow memory at the region pointed to by p to a size newsz.

Parameters

p;	Memory to grow
newsz;	New size to grow to

This function will copy the old bytes to a new memory location if the old memory cannot be grown in place, and will free the old memory. If no more memory is available it will not destroy the old memory.

Returns: NULL if no memory is available, or a pointer to memory with at least newsz bytes.
