Fixed bug #232
------- Comment #2 From Matthias Geissert 2006-05-24 07:54 [reply] -------
See http://dri.sourceforge.net/doc/DRIuserguide.html, section 11.5. There is
written that you need to use RTLD_GLOBAL, since, otherwise, nested open of
dynamic libraries doesn't work. However, This is necassary in this case, since
libGL opens the hardware-specific driver/library. I hope this helps you.

3 SDL_SetEventFilter\- Sets up a filter to process all events before they are posted to the event queue\&. | |

9 .SH "DESCRIPTION" | |
10 .PP | |
11 This function sets up a filter to process all events before they are posted to the event queue\&. This is a very powerful and flexible feature\&. The filter is prototyped as: | |
12 .PP | |
13 .nf | |
14 \f(CWtypedef int (*SDL_EventFilter)(const SDL_Event *event);\fR | |
15 .fi | |
16 .PP | |
17 If the filter returns \fB1\fR, then the event will be added to the internal queue\&. If it returns \fB0\fR, then the event will be dropped from the queue\&. This allows selective filtering of dynamically\&. | |
18 .PP | |
19 There is one caveat when dealing with the \fBSDL_QUITEVENT\fP event type\&. The event filter is only called when the window manager desires to close the application window\&. If the event filter returns 1, then the window will be closed, otherwise the window will remain open if possible\&. If the quit event is generated by an interrupt signal, it will bypass the internal queue and be delivered to the application at the next event poll\&. | |

24 Events pushed onto the queue with \fI\fBSDL_PushEvent\fP\fR or \fI\fBSDL_PeepEvents\fP\fR do not get passed through the event filter\&. | |
