I have actually tested this by running xdpyinfo through ssh to Xvfb,
the result looks like:
Breakpoint 1, ProcQueryExtension (client=0x1ca1e20) at extension.c:253
253 REQUEST_FIXED_SIZE(xQueryExtensionReq, stuff->nbytes);
(gdb) p *client->clientIds
$1 = {pid = 15888,
cmdname = 0x1f957f0 "ssh: /run/user/1000/ssh-control-ajax@localhost:22 [mux",
cmdargs = 0x0}
(gdb) p client->local
$2 = 0
Or, with ssh -S none:
Breakpoint 1, ProcQueryExtension (client=0x1ca1e20) at extension.c:253
253 REQUEST_FIXED_SIZE(xQueryExtensionReq, stuff->nbytes);
(gdb) p *client->clientIds
$1 = {pid = 16366, cmdname = 0x1f95910 "ssh",
cmdargs = 0x1f95930 "-S none -Y localhost"}
(gdb) p client->local
$2 = 0
- ajax
