WaitEvent() locks application (linux) with fix

Archives Forums/BlitzMax Bug Reports/WaitEvent() locks application (linux) with fix

explosive(Posted 2012) [#1]
Hello everybody,

The function WaitEvents() locks the application for exactly 10 seconds on linux (opensuse 12.1, 3.1.9-1.4-desktop, i686, 32Bit).

Fix works as follows:
Change line 270 in "brl.mod/system.mod/system.linux.c" from 
tv.tv_sec=10;

to
tv.tv_sec=0;


Recompile module. Performance of app is now as expected, CPU load still perfectly low.

Maybe someone likes to check the fix on other distros.

Regards, Simon

Hi,

WaitEvents? Do you mean WaitEvent?

WaitEvent is meant to suspend execution until something is posted to the event queue.

Anyway, this works here on Arch Linux:

Import maxgui.drivers

CreateWindow "Test!",0,0,640,480

While WaitEvent()<>EVENT_WINDOWCLOSE
    Print CurrentEvent.ToString()
Wend


...sizing the window causes 'size' events, and closing the window exits immediately.
