/** \file kos/fs_pty.h

\brief Pseudo-terminal virtual file system.
10
11
This file system implements a pseudo-terminal like concept (similar to
12
/dev/pty in Linux). A call to fs_pty_create() will crate two file entries in
13
the VFS, /pty/maXX and /pty/slXX (XX being some hexadecimal number). From
14
there, anybody can open up either end and send data to the other side. Think
15
of it as a simple message passing interface.
16
17
This file system mounts on /pty.

/** \brief Create a new pseudo-terminal.

34
This function creates a new pseudo-terminal, opening up two files in the
35
/pty portion of the VFS.

\param buffer Storage for the name of the PTY, apparently not
38
actually used (but potentially will be fixed at some
39
point). If it was implemented, the name of the PTY
40
would be here on successful return (if not NULL)
41
\param maxbuflen The length of buffer
42
\param master_out A pointer to store the file descriptor for the
43
master end in (must not be NULL)
44
\param slave_out A pointer to store the file descriptor for the slave
45
end in (must not be NULL)
46
\retval 0 On success

\retval -1 On error
