#include <rw/itc/rwtMakeIOUCallback.h>

void cbFunc(RWTIOUResult<int> r);
RWTIOUResult<int> res = ...;
res.addCallback(rwtMakeIOUCallback(cbFunc));

The rwtMakeIOUCallback() helper functions and macros create functors that may be passed to the addCallback() method of an RWTIOUResult<R>. The functor may be created from functions that accept a first argument that is compatible with an RWTIOUResult<R>.

rwtMakeIOUCallback comes in two flavors. First, there is a set of overloaded global function templates. Since not all compilers are able to handle templates to the degree required by these functions, we also provide a corresponding set of macros. The template functions are slightly easier to use and you only have to remember one name. The macros are more portable but they do require more arguments; and because we cannot overload macros, each must have a unique name.

void function(RWTIOUResult<int> result);
RWTIOUResult<int> iouResult = ...;
iouResult.addCallback(rwtMakeIOUCallback(function));

void function(RWTIOUResult<int> result);
RWTIOUResult<int> iouResult = ...;
iouResult.addCallback(rwtMakeIOUCallbackG(void,function));

template <class Redeemable>
inline
RWTFunctor1< RWEscrowHandle<Redeemable> >
rwtMakeIOUCallback(void (*function)(RWTIOUResult<Redeemable>))

rwtMakeIOUCallback(Callee& callee,
         void (Callee::*function)(RWTIOUResult<Redeemable>))

The macros in this section use the following naming conventions for the macro arguments:

function	Global function pointer.
Redeemable	The redeemable type of the RWTIOUResult<R>.
A1	Type name of the first additional argument.
a1	Expression that can be converted to an instance of A1.
A2	Type name of the second additional argument.
a2	Expression that can be converted to an instance of A2.

rwtMakeIOUCallbackG(function, Redeemable)
