58 | /* Emacs can read input using SIGIO and buffering characters itself, | |
59 | or using CBREAK mode and making C-g cause SIGINT. | |
60 | The choice is controlled by the variable interrupt_input. | |
61 | ||
62 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
63 | ||
64 | Emacs uses the presence or absence of the SIGIO macro to indicate | |
65 | whether or not signal-driven I/O is possible. It uses | |
66 | INTERRUPT_INPUT to decide whether to use it by default. | |
67 | ||
68 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
69 | CBREAK mode has two disadvantages | |
70 | 1) At least in 4.2, it is impossible to handle the Meta key properly. | |
71 | I hear that in system V this problem does not exist. | |
72 | 2) Control-G causes output to be discarded. | |
73 | I do not know whether this can be fixed in system V. | |
74 | ||
75 | Another method of doing input is planned but not implemented. | |
76 | It would have Emacs fork off a separate process | |
77 | to read the input and send it to the true Emacs process | |
78 | through a pipe. */ | |
