2.2 Quitting Octave

Built-in Function: exit (status)

Built-in Function: quit (status)

Exit the current Octave session. If the optional integer value status is supplied, pass that value to the operating system as the Octave's exit status. The default value is zero.

Built-in Function: atexit (fcn)

Register a function to be called when Octave exits. For example,

function bye_bye () disp ("Bye bye"); endfunction atexit ("bye_bye");

will print the message "Bye bye" when Octave exits.

Built-in Function: atexit (fcn, flag)

Register or unregister a function to be called when Octave exits, depending on flag. If flag is true, the function is registered, if flag is false, it is unregistered. For example, after registering the function bye_bye as above,

atexit ("bye_bye", false);

will remove the function from the list and Octave will not call the function bye_by when it exits.

Note that atexit only removes the first occurrence of a function from the list, so if a function was placed in the list multiple times with atexit, it must also be removed from the list multiple times.
