- Subject: io.popen(s, 'rb') ?

local pipe = assert(io.popen('ls', 'r'))
local pipe = assert(io.popen('ls', 'rb'))
lua: t:2: ls: Invalid argument
(It doesn't complain about 'rb', it complains about 'ls' !?)
The manpage I found says:
The mode string can also have a 'b' at the end, which is needed
in some systems to open the file in binary mode. This string
is exactly what is used in the standard C function fopen.
Surely binary-mode should work, at least in unix ?
Or does it fail as a warning that windows stdout can't ever
do binary, and unix does binary anyway even with just 'r' ?
('ls' is only an example, the app will involve midi.
I'm using the debian squeeze lua package Lua 5.1.4)
