That is just like writing a script, not calling system calls

find is based on the nftw() call and uses stat semantics - it returns among other things a struct stat.

To answer your question--
You should consider system(). It calls execl for you and then calls waitpid.

Code:
system("find . maxdepth 1 -perm 0644 ");

The reason to call syscalls directly in C instead of using execl() is to eliminate process creation which has a lot of overhead that you have in a shell script. system() and execl() are doing nothing you cannot do in a shell script in this case.

install-menu

install-menu(1) 					      Debian GNU/Linux manual						   install-menu(1)

NAME

       install-menu - Process a menu method and generate the menu files for a window manager or a menu-aware application.

DESCRIPTION

       update-menus(1) computes the list of menu entries and passes it in turn to the menu methods in /etc/menu-methods/. The task of a menu meth-
       ods is to generate menus for a specific window manager.	install-menu provides a generic and customizable way to do that. The documentation
       of the install-menu definition language is available in the Debian Menu manual, a local copy being available in /usr/share/doc/menu/html.

SYNOPSIS

       install-menu [-vh] [--remove] <menu-method>

       Read menu entries from stdin in update-menus --stdout format and generate menu files using the specified menu-method.

       Normally used in menu method scripts as #! /usr/bin/install-menu.

OPTIONS

       -h,--help
	      Show the help message and exit.

       --remove
	      Remove the menu files instead of generating them.

       -v,--verbose
	      Output messages about what the program is doing.

COPYING

       install-menu is distributed under the term of the GNU General Public License version 2, or (at your option) any later version.
