NAME

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

SYNOPSIS

C       int mstat = pvm_mstat( char *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).
