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.
