51 | /* Emacs can read input using SIGIO and buffering characters itself, | |
52 | or using CBREAK mode and making C-g cause SIGINT. | |
53 | The choice is controlled by the variable interrupt_input. | |
54 | ||
55 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
56 | ||
58f3150e YM |
57 | Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros |
58 | to indicate whether or not signal-driven I/O is possible. It uses | |
1a578e9b AC |
59 | INTERRUPT_INPUT to decide whether to use it by default. |
60 | ||
61 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
62 | CBREAK mode has two disadvantages | |
63 | 1) At least in 4.2, it is impossible to handle the Meta key properly. | |
64 | I hear that in system V this problem does not exist. | |
65 | 2) Control-G causes output to be discarded. | |
66 | I do not know whether this can be fixed in system V. | |
67 | ||
68 | Another method of doing input is planned but not implemented. | |
69 | It would have Emacs fork off a separate process | |
70 | to read the input and send it to the true Emacs process | |
71 | through a pipe. */ | |
