NativeMemory.AlignedAlloc(UIntPtr, UIntPtr) Method
Definition
Important

Important
This API is not CLS-compliant.
Allocates an aligned block of memory of the specified size and alignment, in bytes.
public:
static void* AlignedAlloc(UIntPtr byteCount, UIntPtr alignment);[System.CLSCompliant(false)]
public static void* AlignedAlloc(UIntPtr byteCount, UIntPtr alignment);[System.CLSCompliant(false)]
public static void* AlignedAlloc(nuint byteCount, nuint alignment);[<System.CLSCompliant(false)>]
static member AlignedAlloc : unativeint * unativeint -> nativeptr<unit>Parameters
- byteCount
-
UIntPtr
nuint
unativeint
The size, in bytes, of the block to allocate.
- alignment
-
UIntPtr
nuint
unativeint
The alignment, in bytes, of the block to allocate. This must be a power of 2.
Returns
A pointer to the allocated aligned block of memory.
- Attributes
Exceptions
alignment is not a power of two.
Allocating byteCount of memory with alignment failed.
Remarks
This method allows byteCount to be 0 and will return a valid pointer that should not be dereferenced and that should be passed to free to avoid memory leaks.
This method is a thin wrapper over the C aligned_alloc API or a platform dependent aligned allocation API such as _aligned_malloc on Win32.
This method is not compatible with Free(Void*) or Realloc(Void*, UIntPtr). Instead, call AlignedFree(Void*) or AlignedRealloc(Void*, UIntPtr, UIntPtr).
