66 | /* Emacs can read input using SIGIO and buffering characters itself, | |
67 | or using CBREAK mode and making C-g cause SIGINT. | |
68 | The choice is controlled by the variable interrupt_input. | |
69 | ||
70 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
71 | ||
72 | Emacs uses the presence or absence of the SIGIO macro to indicate | |
73 | whether or not signal-driven I/O is possible. It uses | |
74 | INTERRUPT_INPUT to decide whether to use it by default. | |
75 | ||
76 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
77 | CBREAK mode has two disadvantages | |
78 | 1) At least in 4.2, it is impossible to handle the Meta key properly. | |
79 | I hear that in system V this problem does not exist. | |
80 | 2) Control-G causes output to be discarded. | |
81 | I do not know whether this can be fixed in system V. | |
82 | ||
83 | Another method of doing input is planned but not implemented. | |
84 | It would have Emacs fork off a separate process | |
85 | to read the input and send it to the true Emacs process | |
86 | through a pipe. */ | |

445 | /* For unexec to work on Alpha systems, we need to put Emacs' |
446 | initialized data into a separate section from the CRT initialized | |
447 | data (because the Alpha linker freely reorders data variables, even | |
448 | across libraries, so our data and the CRT data get intermingled). | |
449 | ||
450 | Starting with MSVC 5.0, we must also place the uninitialized data | |
451 | into its own section. VC5 intermingles uninitialized data from the CRT | |
452 | between Emacs' static uninitialized data and its public uninitialized | |
453 | data. A separate .bss section for Emacs groups both static and | |
454 | public uninitalized together. | |
455 | ||
456 | Note that unexnt.c relies on this fact, and must be modified | |
457 | accordingly if this section name is changed, or if this pragma is | |
458 | removed. Also, obviously, all files that define initialized data | |
459 | must include config.h to pick up this pragma. */ | |
