Check whether two strings overlap
#include <publib.h> int stroverlap(const char *s, const char *t);
stroverlap checks whether the storage used by two strings overlap (i.e., if they even partially stored in the same place in memory).
stroverlap returns 0 for no overlap, nonzero for any overlap at all.
