Qstl(3)			   Library Functions Manual		       Qstl(3)

NAME
       Qstl - support for Forall, Exists, etc in GNU C++ using STL

SYNOPSIS
       #include	<Qstl.h>

       bool AO(iter,container,exprn) /*	Forall */

       bool EO(iter,container,exprn) /*	Exists */

       bool E1O(iter,container,exprn) /* Exists	a single */

       bool CO(iter,container,exprn) /*	Count */

DESCRIPTION
       These macros implement predicate	calculus operations over Standard Tem-
       plate Library (STL) classes. For	example:

       map<Location,Hatsize,Locationlt>	m;

       AO(i,m,(*i).Hatsize >= 0)

       Note that the macros can	be nested or used in any context that requires
       boolean values.

PORTABILITY
       These macros require GNU	C or GNU C++.

SEE ALSO
       nana-clg(1),  nana(1),  nana(3),	 I(3),	DI(3),	L(3), DL(3), Q(3), and
       nana.info.

       The nana.info page is the primary documentation for this	package.
