.TH pvm_halt 1 "May 1998" "Scilab // Group" "Scilab function"
.so ../sci.an
.SH NAME
pvm_halt - stops the PVM daemon
.SH CALLING SEQUENCE
.nf
[info] = pvm_halt()
.fi
.SH PARAMETERS
.TP 5
info
: integer, status code returned by the routine.
Values less than zero indicate an error.
.SH DESCRIPTION
\fVpvm_halt\fR 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. Uid 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:
rm `( grep $user /etc/passwd || ypmatch $user passwd )
| awk -F: '{print "/tmp/pvmd."$3; exit}'`
For example:
.nf
-->pvm_halt()
ans =
0.
-->pvm_halt()
ans =
- 14.
.fi
Error -14 means: pvm_halt(): Can't contact local daemon
