        value   MEANING
        PvmOk   host is OK
        PvmNoHost       host is not in virtual machine
        PvmHostFail     host is unreachable (and thus possibly failed)

DESCRIPTION

The routine pvm_mstat returns the status mstat of the computer named host with respect to running PVM processes. This routine can be used to determine if a particular host has failed and if the virtual machine needs to be reconfigured. The function pvm_notify() can also be used to notify the caller that a host has failed.

EXAMPLES

C:
        mstat = pvm_mstat( "msr.ornl.gov" );
Fortran:
        CALL PVMFMSTAT( 'msr.ornl.gov', MSTAT )

ERRORS

These error conditions can be returned by pvm_mstat
pvmd not responding.

giving a host name not in the virtual machine.

host is unreachable (and thus possibly failed).
