VOP_LINK(9)		 BSD Kernel Developer's	Manual		   VOP_LINK(9)

NAME
     VOP_LINK -- create	a new name for a file

SYNOPSIS
     #include <sys/param.h>
     #include <sys/vnode.h>

     int
     VOP_LINK(struct vnode *dvp, struct	vnode *vp, struct componentname	*cnp);

DESCRIPTION
     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.

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

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

ERRORS
     [EMLINK]		The file has too many links.

     [EPERM]		The file is immutable.

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