Has anyone managed to make the mount system call work? All I ever
get is a "No device" error, using the syntax of the man page - e. g.,
mount("/dev/od0a", path, 0);
Are there more arguments or a different order?
The umount syscall does not exist in libc.a. There is a unmount
function there -- is its name a typo?leach@neptune.uucp (Tom Leach) (02/24/89)

It appears that the mount (and UNMOUNT) system calls (section 2) use the same format as a Sun (or any BSD system with NFS). The current pages for mount and umount (umount not unmount) are from generic BSD without NFS support. It's the NFS stuff that produced the new version. I've taken BSD source from a microVax (running NFS) and compiled and executed it on our cube with no problems. Therefore, I'm ASSUMING that you can use the Sun man page for mount and unmount with no major problems. (I just gave up and did a system() and executed /etc/mount, so I haven't tested this extensively) Tom Leach leach@oce.orst.edu Internet:leach@OCE.ORST.EDU UUCP:{tektronix, hp-pcd}!orstcs!OCE.ORST.EDU!leach ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Middle-of-the-road, man, it stanks.

If you have a Sun handy, check its MOUNT(2) man page. Check both the 3.x and 4.0 man page; the interface was changed. >The umount syscall does not exist in libc.a.

No. The latter change looks like a change made by Sun when NFS was introduced; since when mounting an NFS file system you don't specify a block special file (since you're not mounting a disk partition), you can't specify that as the sole argument on an unmount operation. "unmount" takes the name of the mount point as the argument, which is a file-system-independent way of indicating what you want to unmount. Given that, and given that NexT supports NFS, they may have adopted the SunOS version of "mount" as well, which permits you to mount things other than block special files (e.g., NFS-exported directories). In any case, if the documentation is still the old 4.xBSD documentation, complain to NExT and mention that the SunOS documentation (which may be distributed with the NFS source distribution) may apply here....
