Fixed bug #633
Description From Michael Stone 2008-09-25 19:27:29 (-) [reply]
To determine whether a pid is occupied with the kill(pid, 0) idiom, you have to
test
#include <signal.h>
#include <errno.h>
kill(pid, 0) < 0 && errno == ESRCH
not just
#include <signal.h>
kill(pid, 0) < 0
otherwise you get incorrect results when pid is running as a different user
(causing kill(pid, 0) to return -1 + EPERM).
src/audio/alsa/SDL_alsa_audio.c is certainly affected by this bug in both
1.2.13 and 1.3-trunk. It probably occurs in other places as well.

To compile and install SDL: 1. Run './configure; make; make install' If you are compiling for Windows using gcc, read the FAQ at: http://www.libsdl.org/faq.php?action=listentries&category=4#42 If you are compiling using Visual C++ on Win32, you should read the file VisualC.html 2. Look at the example programs in ./test, and check out the HTML documentation in ./docs to see how to use the SDL library. 3. Join the SDL developer mailing list by sending E-mail to sdl-request@libsdl.org and put "subscribe" in the subject of the message. Or alternatively you can use the web interface: http://www.libsdl.org/mailing-list.php That's it! Sam Lantinga <slouken@libsdl.org>
