Function: int rl_save_state (struct readline_state *sp)

Save a snapshot of Readline’s internal state to sp. The contents of the readline_state structure are documented in ‘readline.h’. The caller is responsible for allocating the structure.

​

Function: int rl_restore_state (struct readline_state *sp)

Restore Readline’s internal state to that stored in sp, which must have been saved by a call to rl_save_state. The contents of the readline_state structure are documented in ‘readline.h’. The caller is responsible for freeing the structure.

​

Function: void rl_free (void *mem)

Deallocate the memory pointed to by mem. mem must have been allocated by malloc.

​

Function: void rl_replace_line (const char *text, int clear_undo)

Replace the contents of rl_line_buffer with text. The point and mark are preserved, if possible. If clear_undo is non-zero, the undo list associated with the current line is cleared.

​

Function: void rl_extend_line_buffer (int len)

Ensure that rl_line_buffer has enough space to hold len characters, possibly reallocating it if necessary.

​

Function: int rl_initialize (void)

Initialize or re-initialize Readline’s internal state. It’s not strictly necessary to call this; readline() calls it before reading any input.

​

Function: int rl_ding (void)

Ring the terminal bell, obeying the setting of bell-style.

​

Function: int rl_alphabetic (int c)

Return 1 if c is an alphabetic character.

​

Function: void rl_display_match_list (char **matches, int len, int max)

/* Replace the current line buffer contents with TEXT.  If CLEAR_UNDO is

 non-zero, we free the current undo list. */    

void    rl_replace_line (const char *text, int clear_undo)

{

    int len;

    len = strlen (text);

    if (len >= rl_line_buffer_len)

        rl_extend_line_buffer (len);

    strcpy (rl_line_buffer, text);

    rl_end = len;

    if (clear_undo)

        rl_free_undo_list ();

    _rl_fix_point (1);
