NAME

       mktimer - allocate a per-process timer

SYNOPSIS

DESCRIPTION

       The  function is used to allocate a per-process timer using the specified system-wide clock as the timing base.	returns an unique timer ID
       of type used to identify the timer in timer requests (see gettimer(3C)).  specifies the system-wide clock to be used as the timing base for
       the new timer.  specifies the mechanism by which the process is to be notified when the timer expires.

       supports one per-process timer with a of and of

       If is the system causes a signal to be sent to the process whenever the timer expires.

       For the machine-dependent clock resolution and maximum value are and seconds, respectively.  These constants are defined in

RETURN VALUE

       Upon  successful completion, returns a which can be passed to the per_process timer calls.  If unsuccessful, returns a value of and sets to
       indicate the error.

ERRORS

       fails if any of the following conditions are encountered:

	      [EAGAIN]	  The calling process has already allocated all of the timers it is allowed.

	      [EINVAL]	  is not defined, or does not allow the specified notification mechanism.

NAME

       reltimer - relatively arm a per-process timer

SYNOPSIS

DESCRIPTION

       The function sets the of the specified timer to an offset from the current clock setting.

       If  specifies  a  value	argument  with the member equal to zero, the timer is disabled.  updates the it_interval value of the timer to the
       value specified.  Time values smaller than the resolution of the specified timer are rounded up to its resolution; timer values larger than
       the maximum value of the specified timer are rounded down to the maximum value (see mktimer(3C)).

       returns	in  the ovalue parameter a value representing the previous amount of time before the timer would have expired or zero if the timer
       was disabled, together with the previous interval timer period.	The members of ovalue are subject to the resolution of the timer, and  are
       the same values that would be returned by a call.

       The behavior of this function is undefined if value is NULL.

RETURN VALUE

       Upon successful completion, returns zero; otherwise, it returns -1 and sets to indicate the error.

ERRORS

       fails if any of the following conditions are encountered:

	      [EINVAL]	  does	not  correspond to an ID returned by or the value structure specified a nanosecond value less than zero or greater
			  than or equal to 1000 million.

	      [EIO]	  An error occurred while accessing the clock device.
