   8    8  SYNOPSIS
   9    9         #include <time.h>
  10   10  
  11   11         int nanosleep(const struct timespec *rqtp,
  12   12              struct timespec *rmtp);
  13   13  
  14   14         #include <threads.h>
  15   15  
  16   16         int thrd_sleep(const struct timespec *rqtp,
  17   17              struct timespec *rmtp);

  20   20  DESCRIPTION
  21   21         The nanosleep() and thrd_sleep() functions cause the current thread to
  22   22         be suspended from execution until either the time interval specified by
  23   23         the rqtp argument has elapsed or a signal is delivered to the calling
  24   24         thread and its action is to invoke a signal-catching function or to
  25   25         terminate the process. The suspension time may be longer than requested
  26   26         because the argument value is rounded up to an integer multiple of the
  27   27         sleep resolution or because of the scheduling of other activity by the
  28   28         system. But, except for the case of being interrupted by a signal, the
  29   29         suspension time will not be less than the time specified by rqtp, as
  30   30         measured by the system clock, CLOCK_REALTIME.
  31   31  
  32   32  
  33   33         The use of the nanosleep() and thrd_sleep() functions has no effect on
  34   34         the action or blockage of any signal.
  35   35  
  36   36  RETURN VALUES
  37   37         If the nanosleep() or thrd_sleep() function returns because the
  38   38         requested time has elapsed, its return value is 0.
  39   39  
  40   40  
  41   41         If the nanosleep() function returns because it has been interrupted by
  42   42         a signal, the function returns a value of -1 and sets errno to indicate
  43   43         the interruption. If the rmtp argument is non-NULL, the timespec
  44   44         structure referenced by it is updated to contain the amount of time
  45   45         remaining in the interval (the requested time minus the time actually
  46   46         slept). If the rmtp argument is NULL, the remaining time is not
  47   47         returned.
  48   48  
  49   49  
  50   50         If nanosleep() fails, it returns -1 and sets errno to indicate the
  51   51         error.
  52   52  
  53   53  
  54   54         The thrd_sleep() function may fail for identical reasons as the
  55   55         nanosleep() function and returns -1; however, the C11 standard does not
  56   56         define that errno should be set, therefore callers of thrd_sleep()
  57   57         cannot rely on errno being set or staying the same across a call to
  58   58         thrd_sleep() .
  59   59  
  60   60  
  61   61  ERRORS
  62   62         The nanosleep() function will fail if:
  63   63  
  64   64         EINTR
  65   65                   The nanosleep() function was interrupted by a signal.
  66   66  
  67   67  
  68   68         EINVAL
  69   69                   The rqtp argument specified a nanosecond value less than zero
  70   70                   or greater than or equal to 1000 million.
  71   71  
  72   72  
  73   73         ENOSYS
  74   74                   The nanosleep() function is not supported by this
  75   75                   implementation.
