Functions

alignedFree void alignedFree(void* aligned, size_t alignment): Frees aligned memory allocated by alignedMalloc or alignedRealloc. Functionally equivalent to Visual C++ _aligned_free. Do not mix allocations with different alignment.
alignedMalloc void* alignedMalloc(size_t size, size_t alignment): Allocates an aligned memory chunk. Functionally equivalent to Visual C++ _aligned_malloc. Do not mix allocations with different alignment.
alignedRealloc void* alignedRealloc(void* aligned, size_t size, size_t alignment)
alignedReallocDiscard void* alignedReallocDiscard(void* aligned, size_t size, size_t alignment): Reallocates an aligned memory chunk allocated by alignedMalloc or alignedRealloc. Functionally equivalent to Visual C++ _aligned_realloc. Do not mix allocations with different alignment.
isMemoryOverlapping bool isMemoryOverlapping(const(void)* a, ptrdiff_t a_size, const(void)* b, ptrdiff_t b_size): Does memory slices a[0..a_size] and b[0..b_size] have an overlapping byte?
isMemoryOverlapping bool isMemoryOverlapping(const(void)[] a, const(void)[] b): Undocumented in source. Be warned that the author may not have intended to support it.
isPointerAligned bool isPointerAligned(void* p, size_t alignment)
makeVec Vec!T makeVec(size_t initialSize)
makeVec deprecated Vec!T makeVec(size_t initialSize, int alignment): Undocumented in source. Be warned that the author may not have intended to support it.
reallocBuffer void reallocBuffer(T[] buffer, size_t length, int alignment): Used throughout dplug:dsp to avoid reliance on GC. Important: Size 0 is special-case to free the slice. This works a bit like alignedRealloc except with slices as input. You MUST use consistent alignement thoughout the lifetime of this buffer.

Structs

MergedAllocation struct MergedAllocation: Allows to merge the allocation of several arrays, which saves allocation count and can speed up things thanks to locality.
Vec struct Vec(T): Kind of a std::vector replacement. Grow-only array, points to a (optionally aligned) memory location. This can also work as an output range. Vec is designed to work even when uninitialized, without makeVec. Warning: it is pretty barebones, doesn't respect T.init or call destructors. When used in a GC program, GC roots won't be registered.
