GSIZE(3PVM)							  GSIZE(3PVM)

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.

DISCUSSION
  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.
