Find C/C++ Function definitions/prototype	Can't Post

Hi,

I need some help in how to find a C and C++ function declarations using Perl regular expression. This regular expression should be able to detect that a function definition has been encountered.

To be more specific I will take an example:

If we have a C or C++ function:

void XyzFunc(void)
{
}

in C++

void Xyz::XyzFunc(void)
{
}

then the regular expression should be able to detect above function definition.

I wrote a regular expression but the problem i am facing is that 'if' 'while' etc are getting recognized as funcitons. Also some of complex C/C++ statements are also getting recognized as functions.

Let me know if any more information required.

Hi Somesh,

Try googling "perl c++ parser". I did and it looks like the easiest way might be to run your c++ header files through ctags or gcc-xml then deal with that output in your perl program. C++ parsing is non-trivial: don't try it at home. Wink

Good luck,

Larry
