SYNOPSIS


.In sys/param.h
.In sys/vnode.h
.In 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.

HISTORY

The function VOP_CREATE appeared in BSD 4.3 .
