You could something like this:

Code:
# cat input
void function1(arg1, 
   arg33,
   arg2,arg3)

Code:
#!/usr/bin/perl

open FILE, "<".shift or die $!;

while (<FILE>) {
   chomp;
   if(/void ([^ \(])+/ || $f)
     {
     $f=1;
     $cF.=$_ ;
     last if ( /\)\s*$/ );
     }
   }

print "cF:".$cF."\n";

LEARN ABOUT DEBIAN

dh_installinit

DH_INSTALLINIT(1)						     Debhelper							 DH_INSTALLINIT(1)

NAME

       dh_installinit - install init scripts and/or upstart jobs into package build directories

SYNOPSIS

       dh_installinit [debhelperoptions] [--name=name] [-n] [-R] [-r] [-d] [--params]

DESCRIPTION

       dh_installinit is a debhelper program that is responsible for installing init scripts with associated defaults files, as well as upstart
       job files into package build directories.

       It also automatically generates the postinst and postrm and prerm commands needed to set up the symlinks in /etc/rc*.d/ to start and stop
       the init scripts.

FILES

       debian/package.init
	   If this exists, it is installed into etc/init.d/package in the package build directory.

       debian/package.default
	   If this exists, it is installed into etc/default/package in the package build directory.

       debian/package.upstart
	   If this exists, it is installed into etc/init/package.conf in the package build directory.

OPTIONS

       -n, --noscripts
	   Do not modify postinst/postrm/prerm scripts.

       -o, --onlyscripts
	   Only modify postinst/postrm/prerm scripts, do not actually install any init script, default files, or upstart job. May be useful if the
	   init script or upstart job is shipped and/or installed by upstream in a way that doesn't make it easy to let dh_installinit find it.

       -R, --restart-after-upgrade
	   Do not stop the init script until after the package upgrade has been completed. This is different than the default behavior, which
	   stops the script in the prerm, and starts it again in the postinst.

	   This can be useful for daemons that should not have a possibly long downtime during upgrade. But you should make sure that the daemon
	   will not get confused by the package being upgraded while it's running before using this option.

       -r, --no-restart-on-upgrade
	   Do not stop init script on upgrade.

       --no-start
	   Do not start the init script on install or upgrade, or stop it on removal.  Only call update-rc.d. Useful for rcS scripts.

       -d, --remove-d
	   Remove trailing d from the name of the package, and use the result for the filename the upstart job file is installed as in etc/init/ ,
	   and for the filename the init script is installed as in etc/init.d and the default file is installed as in etc/default/ . This may be
	   useful for daemons with names ending in d. (Note: this takes precedence over the --init-script parameter described below.)

       -uparams --update-rcd-params=params
       -- params
	   Pass params to update-rc.d(8). If not specified, defaults will be passed to update-rc.d(8).

       --name=name
	   Install the init script (and default file) as well as upstart job file using the filename name instead of the default filename, which
	   is the package name. When this parameter is used, dh_installinit looks for and installs files named debian/package.name.init,
	   debian/package.name.default and debian/package.name.upstart instead of the usual debian/package.init, debian/package.default and
	   debian/package.upstart.

       --init-script=scriptname
	   Use scriptname as the filename the init script is installed as in etc/init.d/ (and also use it as the filename for the defaults file,
	   if it is installed). If you use this parameter, dh_installinit will look to see if a file in the debian/ directory exists that looks
	   like package.scriptname and if so will install it as the init script in preference to the files it normally installs.

	   This parameter is deprecated, use the --name parameter instead. This parameter is incompatible with the use of upstart jobs.

       --error-handler=function
	   Call the named shell function if running the init script fails. The function should be provided in the prerm and postinst scripts,
	   before the #DEBHELPER# token.

NOTES

       Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple
       instances of the same text to be added to maintainer scripts.
