Hello there jbrown,

For example...


include dll.e
RoutineName = define_c_func( {}, RoutineMemAddress, {C_POINTER}, C_LONG)

--Then you can call it via c_func:

atom retv
retv=c_func(RoutineName,{Params})

Rob said he was thinking of a way to 'undefine' the c func
too in case you dont need that particular routine any longer.

It works pretty good for fairly static methods that will
probably be used throughout the program instances life.

Take care for now,
Al
