DI(3) Library Functions Manual DI(3)NAME
DI - verify assertions in C and C++ code using gdb(1)SYNOPSIS
The DI(exprn) checks that the exprn is true in the same way as assert(3). It is however implemented by generating debugger commands from
the source code and so only works if you run the command under a debugger after source the command file generated by nana(1).
exprn - the expression to be checked.
guard - the expression is normally only checked if the guard is true.
handler - a macro which generates the code that handles the error condition.
param - a parameter which can be passed off to the handler. This can be used for identifying the assertion failure in a space-efficent man-
ner, e.g. by copying it into a register before aborting.
See nana.info for details on configuring the behaviour on error detection, etc. You also need to include the nana library by using -lnana
if you use the default setup.
In addition to the DI, DIG, etc DI.h also provides DN, DNG, etc which are used to check that an expression is never true.

The nana.info file is the primary documentation for this library.

Qstl(3) Library Functions Manual Qstl(3)NAME
Qstl - support for Forall, Exists, etc in GNU C++ using STL
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 */
These macros implement predicate calculus operations over Standard Template Library (STL) classes. For example:
AO(i,m,(*i).Hatsize >= 0)
Note that the macros can be nested or used in any context that requires boolean values.
These macros require GNU C or GNU C++.
