fdtools is a set of tools for working with file
descriptors. The grabconsole program redirects
console messages to a pseudoterminal. The seek0
program rewinds a file descriptor. The setblock
program makes a file descriptor blocking or
nonblocking. The statfile program sets environment
variables according to a file's inode data. The
vc-get, vc-lock, and vc-switch commands manipulate
virtual consoles. The fdtools library provides
grabconsole, seek0, and setblock as C functions.
