mempcpy - memory return-offset-pointer copy

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#define _GNU_SOURCE         /* See feature_test_macros(7) */
#include <string.h>  // see memory.h(3head)

void *mempcpy(size_t n;
              void dest[restrict n], const void src[restrict n],
              size_t n);

DESCRIPTION
