Extract a specific function in C source code
 

Hello,
How can I extract a specific function in C source code and print the function on the command line environment(non-gui),I tried regex, but the match end at the first { .
It is: /((\w+)\s*(\w+)\s*\(([\w\s,<>\[\].=&':\/*]*?)\)\s*(const)?\s*\{([^\}])+\})/.
I don't know how to handle the brace, please help me.
Thank you very much.
Tony
