Hi,

I need help in profiling a C++ CGI script using MS Visual C++ or any other tools. I need to know about the function coverage and function timings.
The normal procedure for profiling exe doesn't seem to work as it is a CGI script expecting a HTTP request.

Thanks

It can just be a normal windows console program, just read from stdin/environment and write to the stdout, nothing much.

Hi,

Thanks for your response.

I need some more clarifications.

The problem is that I need to set up the environment/stdin from where the cgi can read from it. I do not know how to do that.
As I understand this is set up by the web server when it receives an HTTP request.

Just running the exe is of no help, my problem is to invoke the
profiler when the cgi exe is invoked by the webserver.

I don't quite understand what do you mean by "profiling a C++ CGI scipt".  Of course you will need a web server for testing, and I think microsoft personal web server is a good tool for that.  After you properly setup the server, everything else will just be normal C++ coding.  Maybe you could further clarify your needs.

Hi,

I am sorry that I was not very clear about the question.
Well there is no problem with my CGI script or in running it.
It has been developed by a number of people and there is huge amount of redundant code in it. Now I want to find out how efficient the code is, i.e. things like how many times a function/method in the script is being called, how much of CPU time & other resources a particular function is consuming, etc. so that I can improve it's performance.

Microsoft Visual C++ has a tool called profiler which can be used for getting such statistics for all kind of projects. But I am unable to use that for a CGI-Script as the exe file expects that certain CGI environment variables are set, some input in stdin, etc. as usual.

Like the way i attach the VC++ debugger to the script, I want to know how i can do the same for the "profiler" in VC++.
OR
is there any other tools using which i can use to evaluate the performance of a C++ CGI script.

Sorry for the trouble
Thanx
