I actually need to get the file descriptor so that I can pass it to kqueue().

Thanks

Chris,

Assuming you want the contents of a symlink file, use readlink(2).

I am trying to call the open() function on a symlink to get a file descriptor. I need to open the symlink file, not the target. I can use the O_SYMLINK flag on Leopard to get this behavior, but that flag is not available on Tiger. I initially thought O_NOFOLLOW would do what I wanted, but then realized that is not what it is meant to do. It is supposed to cause the open() call to fail if the file is a symlink. It behaves this way on Leopard, but it appears to be broken on Tiger. Calling open() on Tiger seems to just ignore the O_ NOFOLLOW flag.

Any suggestions?

Thanks
