+.\" .Sh DESCRIPTION
+.Sh RETURN VALUE
+If the
+.Fn nanosleep
+function returns because the requested time has elapsed, the value
+returned will be zero.
+.Pp
+If the
+.Fn nanosleep
+function returns due to the delivery of a signal, the value returned
+will be the -1, and the global variable
+.Va errno
+will be set to indicate the interruption.
+If
+.Fa rmtp
+is
+.Pf non- Dv NULL ,
+the timespec structure it references is updated to contain the
+unslept amount (the request time minus the time actually slept).
+.Sh ERRORS
+If any of the following conditions occur, the
+.Nm
+function shall return -1 and set
+.Va errno
+to the corresponding value.
