pgarrigue Posted February 28, 2010 Share Posted February 28, 2010 Hi everybody, I've written a fonction in a dll and I've got a problem when executing the AutoIt script (crash of AutoIt interpreter). Here the code of my DLL : function.h ========== #ifndef _EVAL_CHECKSUM_FULLWINDOW_H #define _EVAL_CHECKSUM_FULLWINDOW_H #ifdef BUILD_DLL /* DLL export */ #define DLL_EXPORT __declspec(dllexport) #else /* EXE import */ #define DLL_EXPORT __declspec(dllimport) #endif #include <direct.h> #include <iostream> using namespace std; extern "C" { DLL_EXPORT short multby2(short input, short *output); }; #endif function.cxx extern "C" { BOOL WINAPI DllMain(HANDLE hinst, DWORD reason, LPVOID lpReserve) { //HInst = (HINSTANCE)hinst; //printf ("Handle de la DLL de DllMain : %d\n", (unsigned int)HInst); switch(reason) { case DLL_PROCESS_ATTACH: printf ("Attachement de la DLL au process \n"); break; case DLL_PROCESS_DETACH: printf ("Déttachement de la DLL du process \n"); break; default : // DLL_THREAD_ATTACH, DLL_THREAD_DETACH break; } return true; } } short multby2(short input, short* output) { cout << "input = " << input << endl; *output = 2*intput; return 0; } dll compilation =============== g++ -c -DBUILD_DLL function.cxx g++ -shared -o mydll.dll function.o -mwindows Here the autoit script : ========================= $dll = DllOpen("mydll.dll") $input = 3; $str = "short;" $struct = DllStructCreate($str) $result = DllCall($dll, "short", "multby2", "short", $input,"ptr",DllStructGetPtr($struct)) What I observed : ================ The script calls the DLL : OK but it seems to have a problem during the return to the autoit script. Any idea ? Thanks Link to comment Share on other sites More sharing options...
jchd Posted February 28, 2010 Share Posted February 28, 2010 There is (at least) a calling convention error:$result = DllCall($dll, "short:cdecl", "multby2", "short", $input,"ptr",DllStructGetPtr($struct)) This wonderful site allows debugging and testing regular expressions (many flavors available).
