Hi,
Does anybody know how to share memory in a DLL with C++Builder 5.0 ?
I need to shared datas inside a DLL called by two differents EXE.
A have read that for MSVC++ the right method is to use #pragma like this :
#pragma data_seg("SHARED")
int MyInt;
#pragma data_seg()
#pragma comment(linker, "/SECTION:SHARED,RWS")
Then, I have found that for C++Builder4.0 the right method is to use #pragma like this :
#pragma option -zRSHSEG // change default data segment name
#pragma option -zTSHCLASS // change default data class name
int MyInt;
But the two methods don't work in C++Builder 5.0.
Another point is that it is not possible to use an exported static variable with __declspec(dllexport).
Thank you in advance for your help !
Regards,
Mathieu
