Allocates a block of memory of the specified size, in bytes.
public:
static void* Alloc(UIntPtr byteCount);[System.CLSCompliant(false)]
public static void* Alloc(UIntPtr byteCount);[System.CLSCompliant(false)]
public static void* Alloc(nuint byteCount);[<System.CLSCompliant(false)>]
static member Alloc : unativeint -> nativeptr<unit>Parameters
- byteCount
-
UIntPtr
nuint
unativeint
The size, in bytes, of the block to allocate.
Returns
A pointer to the allocated block of memory.
- Attributes
Exceptions
Allocating byteCount of memory 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 malloc API.

static member Alloc : unativeint * unativeint -> nativeptr<unit>Parameters
- elementCount
-
UIntPtr
nuint
unativeint
The count, in elements, of the block to allocate.
- elementSize
-
UIntPtr
nuint
unativeint
The size, in bytes, of each element in the allocation.
Returns
A pointer to the allocated block of memory.
- Attributes
Exceptions
Allocating elementCount * elementSize bytes of memory failed.
Remarks
This method allows elementCount and/or elementSize 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 malloc API.
