nap(2)                 (XENIX Compatibility Package)                 nap(2)


   NAME
         nap - suspends execution for a short interval

   SYNOPSIS
         cc [flag ...] file ... -lx
         int nap (long period);

   DESCRIPTION
         The current process is suspended from execution for at least the
         number of milliseconds specified by period, or until a signal is
         received.

   DIAGNOSTICS
         On successful completion, a long integer indicating the number of
         milliseconds actually slept is returned.  If the process received a
         signal while napping, the return value will be -1, and errno will be
         set to EINTR.

   SEE ALSO
         sleep(2)

   NOTES
         This function is driven by the system clock, which in most cases has
         a granularity of tens of milliseconds.
