VOP_LINK — create a new name for a file

       This manual page was originally written by Doug Rabson.

Debian                                            July 24, 1996                                      VOP_LINK(9)

       This links a new name in the specified directory to an existing file.

       Its arguments are:

       dvp       The vnode of the directory.

       vp        The vnode of the file to be linked.

       cnp       Pathname information about the file.

       The  pathname  info  should  not be released on exit because it is done by the caller.  The directory and
       file vnodes should not be released on exit.

       [EMLINK]           The file has too many links.

       [EPERM]            The file is immutable.

       [EXDEV]            A hard link is not possible between different file systems.

VOP_LINK() expects the directory and file vnodes to be locked on entry and will leave the  vnodes  locked
       on return.

       Zero is returned if the file was linked successfully, otherwise an error is returned.
