pvm_delhosts

DELHOSTS(3PVM)							  PVM Version 3.4						    DELHOSTS(3PVM)

NAME

       pvm_delhosts - Deletes hosts from the virtual machine.

SYNOPSIS

       C    int info = pvm_delhosts( char **hosts, int nhost, int *infos )

       Fortran	 call pvmfdelhost( host, info )

PARAMETERS

       hosts   An array of pointers to character strings containing the names of the machines to be deleted.

       nhost   Integer specifying the number of hosts to be deleted.

       infos   Integer	array  of  length nhost which contains the status code returned by the routine for the individual hosts.  Values less than
	       zero indicate an error.

       host    Character string containing the name of the machine to be deleted.

       info    Integer status code returned by the routine.  Values less than nhost indicate partial failure, values less than	1  indicate  total
	       failure.

DESCRIPTION

       The  routine  pvm_delhosts  deletes  the  computers  pointed to in hosts from the existing configuration of computers making up the virtual
       machine.  All PVM processes and the pvmd running on these computers are killed as the computer is deleted.  If pvm_delhosts is  successful,
       info  will  be  nhost.  Partial success is indicated by 1<= info < nhost, and total failure by info < 1.  The array infos can be checked to
       determine which host caused the error.

       The Fortran routine pvmfdelhost deletes a single host from the configuration with each call.

       If a host fails, the PVM system will continue to function and will automatically delete this host from the virtual machine.  An application
       can  be notified of a host failure by calling pvm_notify.  It is still the responsibility of the application developer to make his applica-
       tion tolerant of host failure.

EXAMPLES

       C:
	    static char *hosts[] = {
		 "sparky",
		 "thud.cs.utk.edu",
	    };
	    int status[2];
	    info = pvm_delhosts( hosts, 2, status );

       Fortran:
	    CALL PVMFDELHOST( 'azure', INFO )

ERRORS

       These error conditions can be returned by pvm_delhosts

       PvmBadParam
	      giving an invalid argument value.

       PvmSysErr
	      local pvmd not responding.
