Allocates and zeroes a block of memory of the specified size, in bytes.

static void* AllocZeroed(UIntPtr byteCount);[System.CLSCompliant(false)]
public static void* AllocZeroed (nuint byteCount);[System.CLSCompliant(false)]
public static void* AllocZeroed (UIntPtr byteCount);[<System.CLSCompliant(false)>]
static member AllocZeroed : unativeint -> nativeptr<unit>Parameters
- byteCount
-
UIntPtr
nuint
unativeint
The size, in bytes, of the block to allocate.
Returns
A pointer to the allocated and zeroed 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 calloc API.

static member AllocZeroed : 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 and zeroed block of memory.
- Attributes
Exceptions
Allocating elementCount * elementSize bytes of memory failed.
Remarks
This method allows elementCount and elementSize to be 0. It returns a valid pointer that should not be dereferenced and that should be passed to free to avoid memory leaks.
