• Lifetime of a const string literal returned by a function

  - by Neeraj

  Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

• How to specify dll onload function for mingw32?

  - by aking1012

  I can compile DLLs properly using mingw and do the exports/imports stuff. What I am looking for is defining the dll onload function properly as you would in MS VC products. Google didn't turn up anything. Anyone have any ideas or a link to a tutorial? It was suggested that this code snippet be added to the question: extern "C" DLL_EXPORT BOOL APIENTRY DllMain(HINSTANCE hinstDLL, DWORD Reason, LPVOID LPV) And yes, this is what I am trying to do, but with mingw.

• Function allocation

  - by novice_coder

  Where are functions stored in a C++ program? For example int abc() { //where am I stored? } I know that we can take the address of a function, that means functions are stored somewhere in memory. But I have already read at many places that no memory allocation for functions takes place. I am confused. My question may seem vague to many of you but I can't help.
