Greetings honoured monks,
I'm working on a regex that returns me a list of function names of a c++ file.
(Returns a array of strings or a string )
But there are so many possibilities of function definitions.
E.g. :
are ok :
void CLASS1::Function0 (void){
}
const void CLASS1::Function1 (void)
{
}
const CLASS2::Type CLASS1::Function3 (void){
}
std::vector<std::string>& CLASS1::Function4 (void){
}
const CLASS2::Type<Type2>* CLASS1::Function5 (void){
}

are not ok :
const std::string Class1::Member1 = "";
foo = Class2::function(FOO,BAA);

[download]
etc
All functions (that are ok) should be in the array.
To simplify it, I have set the function parameters to void.
Does there a module exists for parsing c++ source files?
Is there a better way to get the function names without a regex?
my code so far : 
#!/usr/local/bin/perl -w
use strict;
use warnings;
while (<DATA>) {
  chomp();
  my $reg="";
  $reg.="^[a-zA-Z0-9]+";
  $reg.="\\s*";
  $reg.="[^:]*::\\s*";
  $reg.="([^ ]*\\s)?";
  $reg.="([^(]*)";
  $reg.="\\([^)]*\\)[{]?\$";

  print "$2\n" if (/$reg/);
}
__DATA__
void CLASS1::Function0 (void){
}
const void CLASS1::Function1 (void)
{
}
const CLASS2::Type CLASS1::Function3 (void){
}
std::vector<std::string>& CLASS1::Function4 (void){
}
const CLASS2::Type<Type2>* CLASS1::Function5 (void){
}
const std::string Class1::Member1 = ""
" more data ";
std::vector<std::string>& CLASS1::Function4 (void){
    foo = Class2::function(FOO,BAA);
}

I hope the great spirit of monk wisdom can help a unworthy little apprentice like me.
