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).
