Functions
void *	mi_malloc_aligned (size_t size, size_t alignment)
	Allocate size bytes aligned by alignment.

void *	mi_zalloc_aligned (size_t size, size_t alignment)

void *	mi_calloc_aligned (size_t count, size_t size, size_t alignment)

void *	mi_realloc_aligned (void *p, size_t newsize, size_t alignment)

void *	mi_malloc_aligned_at (size_t size, size_t alignment, size_t offset)
	Allocate size bytes aligned by alignment at a specified offset.

void *	mi_zalloc_aligned_at (size_t size, size_t alignment, size_t offset)

void *	mi_calloc_aligned_at (size_t count, size_t size, size_t alignment, size_t offset)

void *	mi_realloc_aligned_at (void *p, size_t newsize, size_t alignment, size_t offset)

Detailed Description

Allocating aligned memory blocks. Note that alignment always follows size for consistency with the unaligned allocation API, but unfortunately this differs from posix_memalign and aligned_alloc in the C library.

Function Documentation

◆ mi_calloc_aligned()

void * mi_calloc_aligned	(	size_t	count,
		size_t	size,
		size_t	alignment )

◆ mi_calloc_aligned_at()

void * mi_calloc_aligned_at	(	size_t	count,
		size_t	size,
		size_t	alignment,
		size_t	offset )

◆ mi_malloc_aligned()

void * mi_malloc_aligned	(	size_t	size,
		size_t	alignment )

Allocate size bytes aligned by alignment.

Parameters

size	number of bytes to allocate.
alignment	the minimal alignment of the allocated memory.

Returns: pointer to the allocated memory or NULL if out of memory. The returned pointer is aligned by alignment, i.e. (uintptr_t)p % alignment == 0.

Returns a unique pointer if called with size 0.

◆ mi_malloc_aligned_at()

void * mi_malloc_aligned_at	(	size_t	size,
		size_t	alignment,
		size_t	offset )

Allocate size bytes aligned by alignment at a specified offset.
