VOP_OLD_CREATE(9) DragonFly Kernel Developer's Manual VOP_OLD_CREATE(9)
NAME
VOP_OLD_CREATE, VOP_OLD_MKNOD, VOP_OLD_MKDIR, VOP_OLD_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_OLD_CREATE(struct vnode *dvp, struct vnode **vpp,
struct componentname *cnp, struct vattr *vap);
int
VOP_OLD_MKNOD(struct vnode *dvp, struct vnode **vpp,
struct componentname *cnp, struct vattr *vap);
int
VOP_OLD_MKDIR(struct vnode *dvp, struct vnode **vpp,
struct componentname *cnp, struct vattr *vap);
int
VOP_OLD_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_OLD_LOOKUP(9) when an object is
being created. If an error is detected when creating the file, then this
memory will be freed. If the file is created successfully, then it will
be freed.
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 filesystem is full.
[EDQUOT] Quota exceeded.
