[MPlayer-cvslog] r29224 - trunk/libvo/gl_common.c

[reimar]

Author: reimar
Date: Thu Apr 23 12:18:32 2009
New Revision: 29224

Log:
Change getdladdr to always use dlopen, dlsym and then dlclose.
Performance is not really important and dlsym(0, ...) is
not defined while the more correct dlsym(RTLD_DEFAULT, ...)
is a GNUism (although POSIX does reserve RTLD_DEFAULT).
