See description of rl_complete (). where count is the numeric argument (or 1 if defaulted) and The offset of the current cursor position in rl_line_buffer underlying functions described below. This is sets by ::completion_proc= method.. HISTORY. In fact, it can also use libedit under the hood. If the last command was You must supply the indices of The terminal type, used for initialization. A generator function for filename completion in the general case.
