why Function Name in DLL so strange ?
-
I got a DLL, in its function declare their is a function: EXPORT int func1(); But when I display it in Dependency Walker, the actual name is something like: _func1@0 This DLL is compiled in visual c++ 6.0, I am wondering if there is an option cause this problem. Thanks

What problem? C functions are decorated with a leading underscore. Check whether you are using
__cdeclor__stdcall.

did you ever look a what the compiler generates ? this is called decorated names, exactly such as your
func1()...

if you want undecorated names, you'll need to use a .DEF file Cleek | Image Toolkits | Thumbnail maker

Hello, This is what the C++ compiler does to your function names. The process is called name mangling[^]. You can use
extern Cto say to the compiler that you only wish to add an underscore to the function name. This disables any overloading..extern "C"
{
void func1();
// more functions here

"decorated names" are more commonly used.
