    Parameters

    ptr
    A pointer to the existing memory block being resized.
    size
    The size of the new memory block.

    Returns

    An untyped pointer to the allocated memory, or if the allocation attempt fails, NULL. Call PR_GetError() to retrieve the error returned by the libc function realloc().

    Description
