+.SH DESCRIPTION
+The
+.BR libsimple_timeval2timespec ()
+converts the value
+.I *tv
+to a
+.B struct timespec
+and stores the result in
+.IR ts .
+.PP
+The
+.BR libsimple_timespec2timeval ()
+converts the value
+.I *ts
+to a
+.BR "struct timeval" ,
+rounding to nearest microsecond,
+and stores the result in
+.IR tv .
+.SH RETURN VALUE
+The
+.BR libsimple_timespec2timeval ()
+function returns 0 on successful completion; otherwise -1 is returned
+and sets
+.I errno
+to indicate the error.
+.PP
+The
+.BR libsimple_timeval2timespec ()
+function does not return a value.
+.SH ERRORS
+The
+.BR libsimple_timespec2timeval ()
+function fail if:
+.TP
+.B EOVERFLOW
+The value
+.I {.tv_sec=TIME_MAX,.tv_nsec=999999500L}
+or a greater value converted, which would lead to overflow.
+The value
+.I {.tv_sec=TIME_MAX,.tv_usec=999999L}
