pvm_gsize - Returns the number of members presently in the named group.

       The routine pvm_gsize returns the size of the group named group.  If there  is  an  error  size  will  be
       negative.

       Since  groups  can  change  dynamically  in  PVM  3.0,  this  routine  can  only  guarantee to return the
       instantaneous size of a given group.

       These error conditions can be returned by pvm_gsize

       PvmSysErr
              pvmd was not started or has crashed.

       PvmBadParam
              giving an invalid group name.

       C:
            size = pvm_gsize( "worker" );

       Fortran:
            CALL PVMFGSIZE( 'group2', SIZE )

       pvm_gsize - Returns the number of members presently in the named group.

       group   Character string group name of an existing group.

       size    Integer  returning  the number of members presently in the group.  Values less than zero indicate
               an error.
