1052 /* Handling errors. | |
1053 | |
1054 If an X error occurs which we are not expecting, we have no alternative | |
1055 but to print it to stderr. It would be nice to stuff it into a pop-up | |
1056 buffer, or to print it in the minibuffer, but that's not possible, because | |
1057 one is not allowed to do any I/O on the display connection from an error | |
1058 handler. The guts of Xlib expect these functions to either return or exit. | |
1059 | |
1060 However, there are occasions when we might expect an error to reasonably | |
1061 occur. The interface to this is as follows: | |
1062 | |
1063 Before calling some X routine which may error, call | |
1064 expect_x_error (dpy); | |
1065 | |
1066 Just after calling the X routine, call either: | |
1067 | |
1068 x_error_occurred_p (dpy); | |
1069 | |
1070 to ask whether an error happened (and was ignored), or: | |
1071 | |
1072 signal_if_x_error (dpy, resumable_p); | |
1073 | |
1074 which will call Fsignal() with args appropriate to the X error, if there | |
1075 was one. (Resumable_p is whether the debugger should be allowed to | |
1076 continue from the call to signal.) | |
1077 | |
1078 You must call one of these two routines immediately after calling the X | |
1079 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT. | |

428 | 1520 |
1521 (x-get-resource "foreground" "Foreground" 'string 'global) | |

1523 is an interface to a C call something like | |

1531 arbitrary application resources, if you really want to. | |
1532 | |
1533 The returned value of this function is nil if the queried resource is not | |
1534 found. If the third arg is `string', a string is returned, and if it is | |
1535 `integer', an integer is returned. If the third arg is `boolean', then the | |
1536 returned value is the list (t) for true, (nil) for false, and is nil to | |
430 | 1537 mean ``unspecified''. |
