.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}
will be stored in
.IR tv .
.PP
The
.BR libsimple_timeval2timespec ()
function cannot fail.
