NAME
      nap - suspend execution for a short interval

SYNOPSIS
      cc [flag . . .] file . . . -lx
      long 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(3c)

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