Bug Help in retrieving the ending line numbers of the functions

Hi! I've a C file which consist of many function definitions with numbers at the beginning as shown below..

Code:
10 void search()
11 {
12 /*body
14 *
15 *
17 *
18 *
40 *
42 *
60 }
90 void func_name()
95 {
99 /*body
100 *
105 *
111 *
112 *
130 *
135 }

I need to retrive the number at which the function begins and ends..
I mean the function 'search' begins at number 10 and ends at number 60.
In the same way the function 'fun_name()' begins at number 90 and ends at 135..
I can somehow get the beginning line number of the functions using grep..
But how can I get the ending line number??
Note: The numbers used will not be in the order, and there might be many opening and closing braces in the functions..

How can I do it??
Thanks in advance.. Smilie

Can you post/attach a sample input file for testing. And you will have to do like parsing way than just using grep, using grep may not cover exactly what we are looking for.

Try:
Code:
awk '/\(\)/&&i==0;/{/{i++}/}/&&i--&&i==0' file

I hope the sample you have posted here doesn't cover all the cases, so we need big file to test our logic.
