/* Emacs can read input using SIGIO and buffering characters itself,

or using CBREAK mode and making C-g cause SIGINT.
|
|
The choice is controlled by the variable interrupt_input.
|
|
|
|
Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
|
|
|
|
Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros
|
|
to indicate whether or not signal-driven I/O is possible. It uses
|
|
INTERRUPT_INPUT to decide whether to use it by default.
|
|
|
|
SIGIO can be used only on systems that implement it (4.2 and 4.3).
|
|
CBREAK mode has two disadvantages
|
|
1) At least in 4.2, it is impossible to handle the Meta key properly.
|
|
I hear that in system V this problem does not exist.
|
|
2) Control-G causes output to be discarded.
|
|
I do not know whether this can be fixed in system V.
|
|
|
|
Another method of doing input is planned but not implemented.
|
|
It would have Emacs fork off a separate process
|
|
to read the input and send it to the true Emacs process

through a pipe. */
