NAME

       pvm_mstat - Returns the status of a host in the virtual machine.

SYNOPSIS

       C    int mstat = pvm_mstat( char *host )

       Fortran   call pvmfmstat( host, mstat )

PARAMETERS

       host    Character string containing the host name.

       mstat   Integer returning machine status:
                    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

       PvmSysErr
              pvmd not responding.

       PvmNoHost
              giving a host name not in the virtual machine.

       PvmHostFail
              host is unreachable (and thus possibly failed).
