29 | /* Emacs can read input using SIGIO and buffering characters itself, | |
30 | or using CBREAK mode and making C-g cause SIGINT. | |
31 | The choice is controlled by the variable interrupt_input. | |
32 | ||
33 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
34 | ||
35 | Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros | |
36 | to indicate whether or not signal-driven I/O is possible. It uses | |
37 | INTERRUPT_INPUT to decide whether to use it by default. | |
38 | ||
39 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
40 | CBREAK mode has two disadvantages | |
41 | 1) At least in 4.2, it is impossible to handle the Meta key properly. | |
42 | I hear that in system V this problem does not exist. | |
43 | 2) Control-G causes output to be discarded. | |
44 | I do not know whether this can be fixed in system V. | |
45 | ||
46 | Another method of doing input is planned but not implemented. | |
47 | It would have Emacs fork off a separate process | |
48 | to read the input and send it to the true Emacs process | |
49 | through a pipe. */ | |
