-.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.
