|
* The pty object provides an interface for communicating with a child process
|
|
* over a pseudo terminal. The child is the host, we act as the TTY terminal,
|
|
* and the kernel is the driver.
|
|
*
|
|
* To use this, create a new pty object and open it. You will start receiving
|
|
* output notifications through the output_cb callback. To communicate with
|
|
* the other end of the terminal, use the kmscon_pty_input method. All
|
|
* communication is done using byte streams (presumably UTF-8).
|
|
*
|
|
* The pty can be closed voluntarily using the kmson_pty_close method. The
|
|
* child process can also exit at will; this will be communicated through the
|
|
* input callback. The pty object does not wait on the child processes it
|
|
* spawns; this is the responsibility of the object's user.
