it is a question without answer for me : how to store a pointer provided by wrapper in B4R ?
what is the need : in several interesting libraries, objects are created and managed by pointer
adaptation of this type of library to B4R is blocked...
in library, if we have also an index by object, we can manage each object in B4R by index and conversion to pointer is done in wrapper.
in others case,
- in wrapper interface, we can convert a pointer to "object" B4R
but an object is stored on the stack and cannot be stored in a global variable (or i didn't find the way to do it).
=> if we have a callback from wrapper with pointer, if wrapper make a conversion to "object" to B4R, i cannot compare it with pointer found in an other sub...
- in wrapper interface, we can convert in a "long" by a "reinterpret_cast<uint32_t>(pointer)
=> in this case i can store pointer in a "long" global variable at creation and i can compare when a callback is coming
this case is...
