Character Input --------------- - Function: int rl_read_key (void) Return the next character available from Readline's current input stream. This handles input inserted into the input stream via RL_PENDING_INPUT (Note: Readline Variables) and `rl_stuff_char()', macros, and characters read from the keyboard. While waiting for input, this function will call any function assigned to the `rl_event_hook' variable. - Function: int rl_getc (FILE *stream) Return the next character available from STREAM, which is assumed to be the keyboard. - Function: int rl_stuff_char (int c) Insert C into the Readline input stream. It will be "read" before Readline attempts to read characters from the terminal with `rl_read_key()'. - Function: int rl_execute_next (int c) Make C be the next command to be executed when `rl_read_key()' is called. This sets RL_PENDING_INPUT. - Function: int rl_clear_pending_input (void) Unset RL_PENDING_INPUT, effectively negating the effect of any previous call to `rl_execute_next()'. This works only if the pending input has not already been read with `rl_read_key()'. - Function: int rl_set_keyboard_input_timeout (int u) While waiting for keyboard input in `rl_read_key()', Readline will wait for U microseconds for input before calling any function assigned to `rl_event_hook'. The default waiting period is one-tenth of a second. Returns the old timeout value.
