NAME

clone − duplicate a fid

SYNOPSIS

Tclone tag[2] fid[2] newfid[2]
Rclone tag[2] fid[2]

DESCRIPTION

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 session and must not have been opened for I/O by an ­open or ­create message.  After a successful ­clone and before any subsequent messages, ­fid and ­newfid are indistinguishable. 

ENTRY POINTS

A ­clone message is generated by any system call that evaluates a path name and by a ­read of a union directory.
