Can someone give me a clue as to the format of the new SVR4 UUCP lockfiles? I've figured out the second and third numbers (major and minor devices numbers), but what is the first number? Also, what book is this in? I didn't purchase *all* the SRV4 hardcopy books, so obviously it's in one I don't have. Emmet P.

The first number is the major device number for the file system the inode of the device came from (ie st_dev in the stat structure). This is primarily to support remote devices under RFS, but also allows for multiple /dev directories (but who would do that? :-)). >Also, what book is this in?

If you have it, look in Chapter 7, Network Services in the section on Basic Networking Utilities, subsection Administrative Support Files (page 7-62 in the Prentiss-Hall book). In general, I think with the way the information is spread around the manuals, any serious SVR4 developer or administrator will need the complete manual set. -- Dave McCracken dcm@dell.dell.com (512) 343-3720 Dell Computer 9505 Arboretum Blvd Austin, TX 78759-7299

You're right, the 2nd and 3rd numbers are the major and minor of the st_dev field of stat. The first number is the major of the st_rdev field. David
