[MPlayer-cvslog] r30843 - trunk/loader/win32.c

[sesse]

Author: sesse
Date: Fri Mar  5 12:11:47 2010
New Revision: 30843

Log:
Support thread handles in WaitForSingleObject.

Some codecs need this for clean shutdown (as opposed to a crash); we don't 
really support timed wait since POSIX doesn't, but it doesn't seem necessary.
