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.

C:
	mstat = pvm_mstat( "msr.ornl.gov" );

Fortran:
	CALL PVMFMSTAT( 'msr.ornl.gov', MSTAT )

These error conditions can be returned by pvm_mstat

PvmSysErr

PvmHostFail
