How do I fetch the function name and parameters of a C function using Python regex

Hi Everybody,

I am new to python and trying to learn it while working.

I need to find out the function name along with the parameters from a list of "*.C" Files using python regular expressions.

Example:

static void FunctionNameInC(const boolean_T *UnitDelay1_l, const
    boolean_T *UnitDelay2_n)
{

Desired output is :

Function Name: FunctionNameInC
ParametrsList: const boolean_T *UnitDelay1_l, const
    boolean_T *UnitDelay2_n

So far what I have tried is

import re
result=re.findall(r'\(\w+','static void FunctionNameInC(const boolean_T *UnitDelay1_l, const boolean_T *UnitDelay2_n)')
print result 

output:

['(const']

which is far from acceptable,how to proceed with this?

(1) Problems I am facing, how do I recognize any line in a "*.c" file as a function definition . I thought of using the sequence "){" as identifying a function name,but my "C" code format is inconsistent at times it is

"){"

and at times it is

")\n{"

, how do I solve this issue in regex expression ,cause when I tried using in between

'\(\n\w+'

it failed horribly.
(2) Assuming problem 1 is over ,how will I backtrack in the string to print the function name,although I have tried using the

"^"

thing ,but to no success.

Any help is highly appreciated.

Nihar.
