VOP_CREATE, VOP_MKNOD, VOP_MKDIR, VOP_SYMLINK — create a file, socket, fifo, device, directory or symlink
Contents
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.
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 4.3BSD.
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.
