Subject: [SDL] [RFC] get_ticks broken on linux
It uses gettimeofday to calculate the timedifference.
Gettimeofday returns current time which is seldom monotonous.
This breaks SDL timer subsystem. (time callbacks and all that
get borked when the time difference ms is suddenly ~ 2^32)
I posted a message about this earlier but got no response.
Some thoughts on this matter would be appreciated.
(Or even an explanation for the lack of interest.)
A patch below would use the posix timers that have been around
since posix 93 and do provide a good source of monotonous time
on linux boxes (and on few others too).
The following patch is also availabe at:
http://www.hut.fi/u/tkyntola/SDL-1.2.9-clockfix.patch
It's against 1.2.9, but I can easily rediffit against
the cvs branch is needed.
cheers,
Tommi Kyntola tommi.kyntola@ray.fi

24 This library is distributed under GNU LGPL version 2, which can be | |
25 found in the file "COPYING". This license allows you to use SDL | |
26 freely in commercial programs as long as you link with the dynamic | |
27 library. | |
28 | |
29 The best way to learn how to use SDL is to check out the header files in | |
30 the "include" subdirectory and the programs in the "test" subdirectory. | |
31 The header files and test programs are well commented and always up to date. | |
32 More documentation is available in HTML format in "./docs/index.html" | |
33 | |
34 The test programs in the "test" subdirectory are in the public domain. | |
