alignedAllocate
(bytes, a)
|
Uses posix_memalign on Posix and
__aligned_malloc on Windows.
|
alignedReallocate
(b, s, a)
|
Forwards to alignedReallocate(b, newSize, platformAlignment) .
Should be used with blocks obtained with allocate otherwise the custom
alignment passed with alignedAllocate can be lost.
|
allocate
(bytes)
|
Forwards to alignedAllocate(bytes, platformAlignment) .
|
deallocate
(b)
|
Calls free(b on Posix and
__aligned_free(b on Windows.
|
reallocate
(b, newSize)
|
Forwards to alignedReallocate(b, newSize, platformAlignment) .
Should be used with blocks obtained with allocate otherwise the custom
alignment passed with alignedAllocate can be lost.

auto buffer = AlignedMallocator .instance .alignedAllocate(1024 * 1024 * 4,
