What's the point of _declspec functions. Or like in a PostMessage bypass you do...

Code:

DWORD PMA = (DWORD)GetProcAddress(LoadLibrary("USER32.DLL"), "PostMessageA")+5;

_declspec(naked) BOOL PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) {
   _asm {
      mov edi, edi
      push ebp
      mov ebp, esp
      jmp[PMA]
   }
}


Why do you have to use the _declsepc(naked), why can you just declare it normally?
