Struct `std.experimental.allocator.mallocator.AlignedMallocator`

Aligned allocator using OS-specific primitives, under a uniform API.



struct AlignedMallocator
;

Fields

Name	Type	Description
`instance`	`shared(AlignedMallocator)`	Returns the global instance of this allocator type. The C heap allocator is thread-safe, therefore all of its methods and `instance` itself are `shared`.

Methods

Name	Description
`alignedAllocate`	Uses `posix_memalign` on Posix and `__aligned_malloc` on Windows.
`alignedReallocate`	On Posix there is no `realloc` for aligned memory, so `alignedReallocate` emulates the needed behavior by using `alignedAllocate` to get a new block. The existing block is copied to the new block and then freed. On Windows, calls `_aligned_realloc(b.ptr, newSize,` `a)`.
`allocate`	Forwards to `alignedAllocate(bytes, platformAlignment)`.
`deallocate`	Calls `free(b.ptr)` on Posix and `__aligned_free(b.ptr)` on Windows.
`reallocate`	Forwards to `alignedReallocate(b, newSize, platformAlignment)`. Should be used with blocks obtained with `allocate` otherwise the custom alignment passed with `alignedAllocate` can be lost.

Example

auto buffer = AlignedMallocator.instance.alignedAllocate(1024 * 1024 * 4,
    128);
scope(exit) AlignedMallocator.instance.deallocate(buffer);
