DEVM_CLK_PUT(9) 						  Clock Framework						   DEVM_CLK_PUT(9)

NAME

       devm_clk_put - "free" a managed clock source

SYNOPSIS

       void devm_clk_put(struct device * dev, struct clk * clk);

ARGUMENTS

       dev
	   device used to acuqire the clock

       clk
	   clock source acquired with devm_clk_get

NOTE

       drivers must ensure that all clk_enable calls made on this clock source are balanced by clk_disable calls prior to calling this function.

       clk_put should not be called from within interrupt context.

NAME

       pvm_hostsync - Get time-of-day clock from PVM host.

SYNOPSIS

       C    #include <sys/time.h>
	    int info = pvm_hostsync( int host, struct timeval *clk,
		 struct timeval *delta )

       Fortran	 call pvmfhostsync( host, clksec, clkusec, deltasec, deltausec, info )

PARAMETERS

       host    TID of host.

       clk     (or clksec and clkusec) Returns time-of-day clock sample from host.

       delta   (or deltasec and deltausec) Returns difference between local clock and remote host clock.

DESCRIPTION

       pvm_hostsync  samples  the  time-of  day clock of a host in the virtual machine and returns both the clock value and the difference between
       local and remote clocks.

       To reduce the delta error due to message transit time, local clock samples are taken before and after reading the remote clock.	 Delta	is
       the difference between the mean local clocks and remote clock.

       Note  that  the	delta time can be negative.  The microseconds field is always normalized to 0..999999, while the sign of the seconds field
       gives the sign of the delta.  For example:
	    3.25 Sec =	3,250000
	    0	     =	0,0
	    -1 uSec  = -1,999999
	    -1 Sec   = -1,000000
	    -1.1 Sec = -2,999000

       In C, if clk or delta is a null pointer, that parameter is not returned.

ERRORS

       If pvm_hostsync is successful, it returns PvmOk.  These error conditions can be returned by pvm_hostsync

       PvmSysErr
	      pvmd not responding.

       PvmNoHost
	      specified host not in virtual machine.

       PvmHostFail
	      host is unreachable (and thus possibly failed)
