NAME

Term::Completion::_POSIX - utility package for Term::Completion using POSIX termios

DESCRIPTION

This utility package contains few methods that are required for Term::Completion to put the terminal in ``raw'' mode and back. This package uses POSIX termios to accomplish this, which should be portable across many UNIX-like systems. It was successfully tested on Solaris and Linux.

Methods

set_raw_tty()
Uses ``POSIX::Termios'' in POSIX and related methods to set the terminal into ``raw'' mode, i.e. switch off the meaning of any control characters like CRTL-C etc. Also the echo of characters is switched off, so that the program has full control of what is typed and displayed.

Uses the ``in'' field of the Term::Completion object to get the input file handle. Won't do anything if this is not a TTY. See also ``-X'' in perlfunc.

reset_tty()
Resets the terminal to its previous state, which was saved in the object's fields ("_tty_XXX").
get_key()
Reads one byte from the input handle. Internally uses ``getc'' in perlfunc.
