From 50cc42ff3d7bc48a436c5a0413459ca7841b505f Mon Sep 17 00:00:00 2001 From: "Venkateswararao Jujjuri (JV)" Date: Wed, 9 Jun 2010 15:59:31 -0700 Subject: 9p: Define and implement TSYMLINK for 9P2000.L Create a symbolic link SYNOPSIS size[4] Tsymlink tag[2] fid[4] name[s] symtgt[s] gid[4] size[4] Rsymlink tag[2] qid[13] DESCRIPTION Create a symbolic link named 'name' pointing to 'symtgt'. gid represents the effective group id of the caller. The permissions of a symbolic link are irrelevant hence it is omitted from the protocol.
