| 1066 | |
| 1067 If an X error occurs which we are not expecting, we have no alternative | |
| 1068 but to print it to stderr. It would be nice to stuff it into a pop-up | |
| 1069 buffer, or to print it in the minibuffer, but that's not possible, because | |
| 1070 one is not allowed to do any I/O on the display connection from an error | |
| 1071 handler. The guts of Xlib expect these functions to either return or exit. | |
| 1072 | |
| 1073 However, there are occasions when we might expect an error to reasonably | |
| 1074 occur. The interface to this is as follows: | |
| 1075 | |
| 1076 Before calling some X routine which may error, call | |
| 1077 expect_x_error (dpy); | |
| 1078 | |
| 1079 Just after calling the X routine, call either: | |
| 1080 | |
| 1081 x_error_occurred_p (dpy); | |
| 1082 | |
| 1083 to ask whether an error happened (and was ignored), or: | |
| 1084 | |
| 1085 signal_if_x_error (dpy, resumable_p); | |
| 1086 | |
| 1087 which will call Fsignal() with args appropriate to the X error, if there | |
| 1088 was one. (Resumable_p is whether the debugger should be allowed to | |
| 1089 continue from the call to signal.) | |
| 1090 | |
| 1091 You must call one of these two routines immediately after calling the X | |
| 1092 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT. | |

| 1520 | |
| 1521 3) If LOCALE is a device, a call | |
| 1522 | |
| 1523 (x-get-resource "foreground" "Foreground" 'string SOME-DEVICE) | |
| 1524 | |
| 1525 is an interface to a C call something like | |

| 428 | 1532 |
| 1533 (x-get-resource "foreground" "Foreground" 'string 'global) | |
| 1534 | |
| 1535 is an interface to a C call something like | |

| 1540 | |
| 3025 | 1541 Note that for `global', no prefix is added other than that of the |
