Guido van Rooij 79bdab6c87 Ttys structures are now allocated dynamically via ttymalloc/ttyfree. ... This inetrface should be used from now on. pseudo device pty xx still keeps its meaning: a maximum of xx ptys is allowed. A ringbuffer is now 2040 bytes long, per Garrett Wollman's request. The changes are inspired by the way NetBSD did it (thanks for that!), though I made it slihghtly different, including the interface so at least 75% of the allocated space is deallocated when the tty is closed. Note further that it is easy to modify the ringbuffer length runtime. This will have to wait untill some later date... -Guido		1994-03-02 20:28:38 +00:00
