#include <stdio.h>

/*
 * MOVE_ARGV(argv, argc, srcArray, dstArray, len);
 *
 * Moves an argv pointing into portions of the source string, into the
 * (presumably larger) destination string. It does this by copying
 * the contents of the array, then adjusting each element of the argv.
 * since the two strings may not be in contiguous memory, we have to
 * work with offsets.
