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. Important: alignedMalloc(0) does not necessarily return null, and its result _has_ to be freed with alignedFree.

alignedRealloc

void* alignedRealloc(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. Important: alignedRealloc(p, 0) does not necessarily return null, and its result _has_ to be freed with alignedFree.

alignedReallocDiscard

void* alignedReallocDiscard(void* aligned, size_t size, size_t alignment)

Same as alignedRealloc but does not preserve data.

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, int alignment)

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.
