pvm_halt
stops the PVM daemon
Calling Sequence
[info] = pvm_halt()
Arguments
- info
integer, status code returned by the routine. Values less than zero indicate an error.
Description
pvm_halt kills all PVM tasks, all the remote daemons, and the
local daemon. If the master pvmd is killed manually it should be
sent a SIGTERM signal to allow it to kill the remote
pvmds and clean up various files.
The pvmd can be killed in a manner that leaves the file
/tmp/pvmd.uid behind on one or more hosts
(the uid suffix is the numeric user ID from
/etc/passwd) of the user.
This will prevent PVM from restarting on
that host. Deletion of this file will fix this problem and
it can be done as follows:
rm `( grep $user /etc/passwd || ypmatch $user passwd )
| awk -F: '{print "/tmp/pvmd.";$3;exit}'`
For example:
-->pvm_halt() ans = 0. -->pvm_halt() ans = - 14.
Error -14 means: pvm_halt(): Can't contact local daemon
