Summary
The PROCESSHANDLE_COMPARE_ procedure compares two process handles and
reports whether they are identical, represent different processes of the same process
pair, or different.
PROCESSHANDLE_COMPARE_ is primarily useful for determining whether
processes form a process pair. You can determine whether two process handles are
identical by doing a ten-word unsigned comparison.

Parameters
status returned value
INT
returns the result of the comparison. Valid values are:
0 Process handles are unrelated.
1 Process handles are not identical but designate a process pair.
2 Process handles are identical.
processhandle-1 input
INT .EXT:ref:10
is one of the process handles to be compared.
#include <cextdecs(PROCESSHANDLE_COMPARE_)>
