+.SH DESCRIPTION
+The
+.BR libsimple_difftimespec ()
+and
+.BR libsimple_difftimeval ()
+functions calculates the diffence of
+.I minuend
+and
+.I subtrahend
+.RI ( minuend
+is subtracted by
+.IR subtrahend )
+and stores the result in
+.IR diff .
+.SH RETURN VALUE
+The
+.BR libsimple_difftimespec ()
+and
+.BR libsimple_difftimeval ()
+functions return 0 on successful completion;
+otherwise, \-1 is returned and
+.I errno
+is set to indicate the error.
+.SH ERRORS
+The
+.BR libsimple_difftimespec ()
+and
+.BR libsimple_difftimeval ()
+functions fail if:
+.TP
+.B ERANGE
+The result is too large or too small to be stored; if the
+result is too large
+.I *diff
+will be set to
+.I {.tv_sec=TIME_MAX,.tv_nsec=999999999L}
+for the
+.BR libsimple_difftimespec ()
+function and to
+.I {.tv_sec=TIME_MAX,.tv_usec=999999L}
+for the
+.BR libsimple_difftimeval ()
+function, if the result is too small
+.I *diff
+will be set to
+.I {.tv_sec=TIME_MIN,.tv_nsec=0}
+for the
+.BR libsimple_difftimespec ()
+function and to
+.I {.tv_sec=TIME_MIN,.tv_usec=0}
+for the
+.BR libsimple_difftimeval ()
+function.
