Hi, this might be a silly question, but I need to know if for the code below, if i can extract the cvCaptureFromCAM() function from the highgui.lib and paste it in my code so that I can rename it to camcapture() and then call that within my program without just including the highgui library file at the beginning of the code file:

<br />
CvCapture * pCapture = 0;<br />
<br />
<br />
//Initialize video capture<br />
pCapture = cvCaptureFromCAM( CV_CAP_ANY );

Many Thanks

Note that OpenCV was born in Intel, but now has been released to the open-source community.

Said that, technically you can simply get the source code and extract what you want, but you should think about license infringements!

Libraries are compiled so you won't be able to get the source code for a function out of one.

I have no idea what you're trying to do and why but one way of effectively renamining a function is to implement a small shim function that doesn't do a lot - it just calls another function. However you'll also need to wrap any types it returns in other classes or abstract data types otherwise you'll spend the rest of your life casting.

So my advice would be suck it up - just include the header and link with the library, it's less pain in the long run.
