Important

This API is not CLS-compliant.

Reallocates a block of memory to be the specified size, in bytes.

public:
 static void* Realloc(void* ptr, UIntPtr byteCount);

[System.CLSCompliant(false)]
public static void* Realloc (void* ptr, nuint byteCount);

[System.CLSCompliant(false)]
public static void* Realloc (void* ptr, UIntPtr byteCount);

[<System.CLSCompliant(false)>]
static member Realloc : nativeptr<unit> * unativeint -> nativeptr<unit>

Parameters

ptr: Void*

The previously allocated block of memory.

byteCount: UIntPtr
nuint

unativeint

The size, in bytes, of the reallocated block.

Returns

Void*

A pointer to the reallocated block of memory.

Attributes: CLSCompliantAttribute

Exceptions

OutOfMemoryException

Reallocating byteCount of memory failed.

Remarks

This method acts as Alloc(UIntPtr, UIntPtr) if ptr is null.

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 realloc API.
