Uh ? What is a String* ? Either it is a CString or a std::string but I never heard about a String. BTW, the pointer seems strange in that case.

In brief, you have to give more info if you want an answer.

I've no idea, but Windows has a String structure that is used by the Version API. Java has a String class, but this would be the wrong forum for that (like that has ever stopped anyone).

That's fine. It matters not what platform you are using. toxcct's point about casting to a const void* is what's important.

even the problem told by cedric is true, here is what you have to know about LPCVOID :

L-P-C-VOID stands for long-pointer-const-void, so, const void* ; and you certainly know that any pointer can be casted into void*

Hello everyone,

Suppose we have the source codes, how to get all invoked system API (like printf, open, etc.) other than program self-defined API? Are there any existing tools?

Either on Windows or on Linux platform is ok.

thanks in advance,
George

i'm sorry to say that printf(), open() and such functions are not system APIs at all !!! they are C runtime...

system APIs are those defined by the OS, like ShellExecute() for instance.

Sorry that I may not make myself understood. I mean the APIs which are invoked by my program, but not implemented by my program.

regards,
George

even that, printf is not defined by windows, but by the C runtime (printf() is plateform independant - you can use it on unix, linux, windows - even if its implementation is different between the systems).

i repeat myself : a system API is something that is defined by the system (windows, solaris, red hat, etc...) and interfaced to you programmer so that you can use the system functionnalities...

I may use a wrong terminology, I mean the functions which are used by not defined by my program. Clear now?

So from where you get the Defination of that function at runtime!

Hi Alok,

I am not very sure about your points. I mean I only want to get the name and prototype (parameter list and return type) of all dependent system function, not the definition (i.e. implementation). Any comments?

regards,
George

The only thing I know of that even remotely resembles an answer would be the profiler. It shows all functions that get called. You would have to separate out the system functions vs. user functions, though.

Yes, you are right -- I want to distinguish user function and system function. But what is remotely resembles? A tool provided by Visual Studio or something?

It means it is not a direct answer to your question.

Yes, the profiler comes with VS.

Thank you DavidCrow!

Is there a tool called profiler in Visual Studio 2003? I can not find it from the Tools sub-menu. Could you provide more detailed information please?

regards,
George

Hi DavidCrow,

I have found that in the build menu of Visual Studio 2003, there is nothing called profier. Which IDE are you using?

George
