Struct std.experimental.allocator.mallocator.AlignedMallocator

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

struct AlignedMallocator ;

Fields

NameTypeDescription
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

NameDescription
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.ptr) on Posix and __aligned_free(b.ptr) 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.

Example

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