NAME

     VOP_CREATE, VOP_MKNOD, VOP_MKDIR, VOP_SYMLINK — create a file, socket, fifo, device,
     directory or symlink

SYNOPSIS

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

     int
     VOP_CREATE(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp,
         struct vattr *vap);

     int
     VOP_MKNOD(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp,
         struct vattr *vap);

     int
     VOP_MKDIR(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp,
         struct vattr *vap);

     int
     VOP_SYMLINK(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp,
         struct vattr *vap, char *target);

DESCRIPTION

     These entry points create a new file, socket, fifo, device, directory or symlink in a given
     directory.

     The arguments are:

     dvp     The locked vnode of the directory.

     vpp     The address of a variable where the resulting locked vnode should be stored.

     cnp     The pathname component created.

     vap     The attributes that the new object should be created with.

     target  The pathname of the target of the symlink.

     These entry points are called after VOP_LOOKUP(9) when an object is being created.

LOCKS

     The directory, dvp will be locked on entry and must remain locked on return.  If the call is
     successful, the new object will be returned locked.

RETURN VALUES

     If successful, the vnode for the new object is placed in *vpp and zero is returned.
     Otherwise, an appropriate error is returned.

ERRORS

     [ENOSPC]           The file system is full.

     [EDQUOT]           The user's file system space or inode quota would be exceeded.
