Ugh. Exporting global variables as part of the ABI is generally not such a good idea. Perhaps it is better to use functions to acquire and release the input mutex instead? Also, using TLS (i.e. __thread variables) isn't portable. That mechanism certainly isn't supported by all platforms supported by Xorg. _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
