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.
