CLONE(5) File Formats Manual CLONE(5)
clone - duplicate a fid
Tclone tag fid newfid
Rclone tag fid
The clone request carries as arguments an existing fid and a proposed
newfid (which must not be in use) that the client wishes to associate
with the same file as fid. The fid must be valid in the current ses-
sion and must not have been opened for I/O by an open or create mes-
sage. After a successful clone and before any subsequent messages, fid
and newfid are indistinguishable.
A clone message is generated by any system call that evaluates a path
name and by a read of a union directory.
