Hello kevin..

I am really very sorry.But i work in samsung india.I am not sure if i can post the entire code as my company is very strict in this.

And as i told i am new in perl and am not sure whether am doing it right way.I just hope u can give me some idea in this matter becoz the folder which contains .c & .h files is very big and there is no regular pattern to find out if it is a function or not. So if u could help me with it i would greatly appreciate.

Thanks & Regards

I am not familiar enough with C structure to help figure this out.
