Term::Completion::_readkey - utility package for Term::Completion using Term::ReadKey
This utility package contains few methods that are required for Term::Completion to put the terminal in "raw" mode and back. This package uses Term::ReadKey to accomplish this, which should be portable across many systems.
ReadMode 4 to set the terminal into "raw" mode,
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.
Resets the terminal to its previous state,
Reads one byte from the input handle.
Determine the terminal size with
GetTerminalSize and return the list of columns and rows (two integers).
