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  re-
	     turned  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  com-
     puter is deleted.	If pvm_delhosts is successful, info will be nhost.  Par-
     tial  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  er-
     ror.

     The  Fortran  routine pvmfdelhost deletes a single host from the configura-
     tion with each call.

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