Sorry, Thanks for asking. On the write, errno = 2 and strerrno(errno) returns "No such device or file".
On the read, errno = 35 and strerrno(errno) returns "Resource temporarily unavailable". Clearly the write is the issue, but the errno isn't making sense to me.

What shows up in errno when this occurs? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
