NAME
       reltimer - relatively arm a per-process timer

SYNOPSIS
DESCRIPTION
       The function sets the of the specified timer to an offset from the cur‐
       rent 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.
