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.
