Process Executable

• The exe entry points to the executable file being run in a process.
• Typically the program executable name is passed as the first element of the argument list.
• Using the exe entry in the /proc file system is a more reliable way to determine which executable is running.
• The function get_executable_path in the http://siber.cankaya.edu.tr/SystemsProgramming/cfiles/get-exe-path.cprogram (See Fig. 10.5) determines the path of the executable running in the calling process by examining the symbolic link /proc/self/exe.
