I doesn't look like Darwin/MacOSX has an O_DIRECT option to disable caching on the file at open time. Does MacOSX/Darwin have a way to disabling caching on a per-mountpoint basis? I got two, independant suggestions to try fcntl(fd, F_NOCACHE, 1). Execellent! But before I go trying to re-compile these applications, I'm still wondering if there is any way to limit the ubc like in Tru64...

Limit in what way? -Shawn _______________________________________________ Do not post admin requests to the list. They will be ignored.
