PHP is written in C (and most of the extensions you write will be in C) so there really isn't anything to do... if you have a function in C that you would like to make available to userspace scripts, just call it from a PHP_FUNCTION. The only issue you will have to deal with is converting parameters and return values between zend values and the respective C types. Luckily, unless you are dealing with structs, this too should be relatively simple. Hope that helps! Hi Pedro, wrapping C functions shouldn’t be an issue at all.

Do you know some article that explains "wrappping c functions"?. I think that the process will be very similar but I don't know clearly how to do it, what do you think?.

I may have a reason to port an existing C++ extension to Windows so I'll likely be researching the Windows build process quite a bit. I'll make sure to write something up on that topic if I do end up doing it. Hi Mark, thanks for the feedback.
