how to get all invoked system API of a program

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.

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?

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

How get net screen size?

IlanTal20-Jul-06 1:40

I've got an application which I want to fit into the y dimension of the screen. The function:
cyMon = ::GetSystemMetrics( SM_CYSCREEN);
gives me the screen dimension, but I want the net dimension not including the task bar, if the task bar isn't being auto-hidden.
I see that if I hit the maximize button, the system is clever enough to take into consideration whether or not the task bar is displayed.
If I could somehow get the system to tell me what its maximize size it, that would give me the answer. The GetSystemMetrics gives me the same answer, with and without the task bar.
Does anyone know the appropriate call?

Thanks,
Ilan

You need to use SystemParametersInfo with the SPI_GETWORKAREA value: Retrieves the size of the work area on the primary display monitor. The work area is the portion of the screen not obscured by the system taskbar or by application desktop toolbars. The pvParam parameter must point to a RECT structure that receives the coordinates of the work area, expressed in virtual screen coordinates.

why not call ShowWindow(SW_MINIMIZE)after your ::PostMessage commands?

You can accomplish this in three calls then...the PostMessage commands you have (will minimize all windows except the dialog calling it).

Then use ShowWindow(SW_MINIMIZE) to minimize the current window.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
