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

PvmSysErr
pvmd not responding.
PvmNoHost
giving a host name not in the virtual machine.
PvmHostFail
host is unreachable (and thus possibly failed).
