So I managed to port all C++ functions to pharo, which basically includes the following
Not full definition of function open() lseek() close() mmap() I have tested them all, they all return proper values from inside Pharo and Pharo does not crash. it seems also that mmap works because it returns a void pointer as it should. This pointer points to the shared memory where I have put the string "hello" from another C++ program that has shared the memory . So how can from Pharo take the void pointer "(void*)@ 16rFFFFFFFF" and retrieve the string "hello" that it points to ? Essentially I want to dereference the pointer I tried to send the message fromCString to the void pointer (ExternalData) but it crashed Pharo. Another question, is it possible to cast a pointer ? (I do this with C++ programm) so can I cast from pharo the void pointer to a string pointer ? I have also no idea if the void pointer points to a proper memory address , the documentation says that all pointers live in head but I have no way to confirm this. I am so close to sharing memory between Pharo and C++ that I can smell it :D
