Detailed Description

This file contains macros that simplify the wrapping of aqbanking's data types in a C++ class. The macros assume the following:

• The wrapped C type is available as a typedef "wrapped_type"
• The pointer to the wrapped C object is called m_ptr

The only additional assumptions are necessary in the AB_CXXWRAP_CONSTRUCTORS() macro.

#define AB_CXXWRAP_CONSTRUCTOR0	(		cxxname,
			cprefix
	)

Value:

cxxname()                                                                                 \
        : m_ptr(cprefix##_new()) {}

Wraps the default C++ constructor with zero arguments. This macro only works if FOO_new() is available. Some of the FOO_new() functions take additional arguments, in which case this macro doesn't work.

  { return m_ptr; }

Wraps the set of C++ constructors, destructor, and assignment operator.

This macro additionally assumes that the C type FOO has a set of constructor/ destructor/ copy functions which are called FOO_free() and FOO_dup(), respectively.
