NAME
memrev - reverse an array in place

SYNOPSIS
#include <publib.h>
void *memrev(void *block, size_t elsize, size_t elnum);

DESCRIPTION
memrev will reverse an array, by swapping the contents of its elements.

RETURN VALUE
memrev returns its first argument.

EXAMPLE
To reverse an integer array one might do the following.

int array[4] = { 1, 2, 3, 4 };
memrev(array, sizeof(array[0]), 4);
