The function readline () prints a prompt and then reads and returns a single line of text from the user. The line readline returns is allocated with malloc () ; you should free () the line when you are done with it. The declaration for readline in ANSI C is. char *readline (char * prompt );
It allows users to move the text cursor, search the command history, control a kill ring (a more flexible version of a copy/paste clipboard) and use tab completion on a text terminal. As a cross-platform library, readline allows applications on various systems to exhibit identical line-editing behavior.

ReadLine() method reads and only returns the string from the stream output device (console) until a newline character is found. If we want to read a character or numeric value from the user, we need to convert the string to the appropriate data sets. Syntax.
I've got a question about Readline Library.
I want to know if Readline can autocomplete filename from directories in a C program ?
I've searched and only seen command name completion.
thanks in advance.
EDIT: I've copy filename in an array. These as functions that I use : in the file rline.c, char *command_generator,char **tab_completion (const char *text, int start, int end),void initialize_readline (). I think I have to use char * filename_completion_function (char *text, int state) ? When I type on "tab" key, it calls nothing, bind() didn't seem to be used. Do you know if I use right functions ? thanks !!
