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.
