Andreas Kling	e6fc84e234	Kernel: Make /proc/PID/fds display something useful for character devices.	2019-01-21 02:33:01 +01:00
Andreas Kling	9dd29f9aa9	Add a PTY multiplexer (/dev/ptmx) device. ... When you open /dev/ptmx, you get a file descriptor pointing to one of the available MasterPTY's. If none are available, you get an EBUSY. This makes it possible to open multiple (up to 4) Terminals. :^) To support this, I also added a CharacterDevice::open() that gets control when VFS is opening a CharacterDevice. This is useful when we want to return a custom FileDescriptor like we do here.	2019-01-16 13:39:32 +01:00
Andreas Kling	310a5f4199	Let each MasterPTY create its slave.	2019-01-16 02:11:50 +01:00
Andreas Kling	e452303c66	Allow character devices to block write attempts until there is more space.	2019-01-15 09:17:22 +01:00
Andreas Kling	2f74c2f430	Add basic PTY support. ... For now, there are four hard-coded PTYs: /dev/pt{m,s}[0123] Use this in the Terminal to open a pty pair and spawn a shell.	2019-01-15 06:30:19 +01:00
