Can anybode suggest me where to find the source code for system calls itself?
Download the libc source code of the appropriate system. You'll find libc sources for Linux, bsd and Solaris on the net.

When ever we quit a file or save and quit a file,
Give some context. Quit and save aren't system calls either. Do you mean typical commands from the file menu? No. The application calls close(). The OS itsself takes care about writing the actual data to disk. Typically it won't write the contents to disk immediately but just send them to some buffer which is cleaned whenever the disk comes idle or the filesystem is unmounted.

pdebuild-user-mode-linux

pdebuild-user-mode-linux(1)					     pbuilder					       pdebuild-user-mode-linux(1)

NAME

       pdebuild-user-mode-linux - pbuilder-user-mode-linux way of doing debuild

SYNOPSIS

       pdebuild-user-mode-linux [pdebuild-user-mode-linux options] -- [pbuilder-user-mode-linux options]

DESCRIPTION

       A  convenience  program	for  pbuilder-user-mode-linux which invokes pbuilder after obtaining appropriate root privilege in a Debian source
       directory.  One must be inside the source tree containing the debian directory, in order to make it work.

PDEBUILD OPTIONS

       --buildsourceroot [fakeroot]
	      The command used to gain root privilege for invoking dpkg-buildpackage

       --auto-debsign

	      Invoke debsign at the end of pdebuild process.

       --debsign-k [key-id]

	      Pass -k option to debsign to specify which keyid to sign.

       --buildresult [Directory for build results]

	      The place which build result is stored.

       --configfile [Extra config file to use]

	      The configuration file is used, but not passed on to pbuilder-user-mode-linux.

       --debbuildopts [options to pass to dpkg-buildpackage]

	      The space-delimited list of options are passed to dpkg-buildpackage.  This option appends to pbuilder option --debbuildopts and  may
	      also be used to reset the list of options by passing the empty string.

       --use-pdebuild-internal
	      Uses a different implementation of pdebuild, which calls clean and build inside the chroot, using bind-mounts.

	      pdebuild-internal tries to run debian/rules clean inside the chroot.  To achieve the goal, the working directory is passed on inside
	      the chroot, in the form of bind-mounting and debuild is run.

	      This option will not protect the working directory and its parent directories from the build scripts.

       -- [pbuilder options]

	      After the -- symbol, an arbitrary number of pbuilder options can be specified.  See  pbuilder-user-mode-linux.1  for  full  list	of
	      options.

	      There is an exception that --buildresult needs to be specified as pdebuild option before the -- to be effective.

FILES

       /etc/pbuilderrc
	      The configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.

       /usr/share/pbuilder/pbuilderrc
	      The default configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.

       ${HOME}/.pbuilderrc
	      Configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux, overrides what is written in /etc/pbuilderrc
