NAME

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

SYNOPSIS

       C    int size = pvm_gsize( char *group )

       Fortran   call pvmfgsize( group, size )

PARAMETERS

       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.

DESCRIPTION

       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.

EXAMPLES

       C:
            size = pvm_gsize( "worker" );

       Fortran:
            CALL PVMFGSIZE( 'group2', SIZE )

ERRORS

       These error conditions can be returned by pvm_gsize

       PvmSysErr
              pvmd was not started or has crashed.

       PvmBadParam
              giving an invalid group name.
