NAME
       memoverlap - check whether two memory blocks overlap

SYNOPSIS
       #include <publib.h>
       int memoverlap(const void *t, size_t ts, const void *s, size_t ss);

DESCRIPTION
       memoverlap  checks  whether the memory blocks t--(t+ts-1) and s--(s+ss-1) overlap.  Neither pointer argument may be NULL, but the sizes may
       be 0.  The memory blocks can be arbitrary, they do not have to be part of the same array.  Therefore, this function  hides  the	unportable
       pointer comparison that one would otherwise rely on.

RETURN VALUE
       memoverlap returns 0 if the blocks do not overlap, and nonzero if they do.
