memrev

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

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

memrev returns its first argument.

To reverse an integer array one might do the following.

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

This will result in the array being { 4, 3, 2, 1 }.

publib(3), strrev(3), memshuffle(3)
