.SH DESCRIPTION
The
.BR libsimple_cmptimespec ()
and
.BR libsimple_cmptimeval ()
functions compares the values of
.I a
and
.IR b ,
returning a value indicating which is larger, if any.
.SH RETURN VALUE
The
.BR libsimple_cmptimespec ()
and
.BR libsimple_cmptimeval ()
functions return \-1 if
.I a
is less than
.IR b ,
+1 if
.I a
is greater than
.IR b ,
and 0 otherwise.
.SH ERRORS
The
.BR libsimple_cmptimespec ()
and
.BR libsimple_cmptimeval ()
functions cannot fail.
