GNU Readline library ¶
* void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler)
- Set up the terminal for readline I/O and display the initial expanded value of prompt. Save the value of lhandler to use as a function to call when a complete line of input has been entered. The function takes the text of the line as an argument.
* void rl_callback_read_char (void)
- Whenever an application determines that keyboard input is available, it should call rl_callback_read_char(), which will read the next character from the current input source. If that character completes the line, rl_callback_read_char will invoke the lhandler function saved by rl_callback_handler_install to process the line. Before calling the lhandler function, the terminal settings are reset to the values they had before calling rl_callback_handler_install. If the lhandler function returns, the terminal settings are modified for Readline's use again. EOF is indicated by calling lhandler with a NULL line.
* int rl_complete (int ignore, int invoking_key)
- Complete the word at or before point. You have supplied the function that does the initial simple matching selection algorithm (see rl_completion_matches()). The default is to do filename completion.
* rl_compentry_func_t * rl_completion_entry_function
- This is a pointer to the generator function for rl_completion_matches(). If the value of rl_completion_entry_function is NULL then the default filename generator function, rl_filename_completion_function(), is used.
* rl_forced_update_display()
- this redraws the readline prompt, nothing else works with the above commands
