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.

◆ 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, or if the alignment is not a power of 2 (including 0). The size is unrestricted (and does not have to be an integral multiple of the alignment). The returned pointer is aligned by alignment, i.e.
(uintptr_t)p % alignment == 0. Returns a unique pointer if called with size 0.
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.

◆ 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.
- Parameters
-
| size | number of bytes to allocate. |
| alignment | the minimal alignment of the allocated memory at offset. |
| offset | the offset that should be aligned. |
- Returns
- pointer to the allocated memory or NULL if out of memory, or if the alignment is not a power of 2 (including 0). The size is unrestricted (and does not have to be an integral multiple of the alignment). The returned pointer is aligned by alignment, i.e.
(uintptr_t)p % alignment == 0. Returns a unique pointer if called with size 0.
