+.Sh SYNOPSIS
+.Fd #include <time.h>
+.Ft int
+.Fn nanosleep "const struct timespec *rqtp" "struct timespec *rmtp"
+.\" .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.
+.Bl -tag -width Er
+.It Bq Er EFAULT
+Either
