Hi,
Here is a function:
function tcp_mt.__index.receive(self, pattern, extra)
if self.closed then return nil, "closed" end
if self.reading then return nil,"socket busy reading" end
self.reading = true
self.rtimedout = false
if self.timeout and self.timeout > 0 then
self.rtimer = timer.add_timer(function()
self.rtimedout = true
if self[YIELD_R] then
coroutine.resume(self[YIELD_R])
end
end, self.timeout)
end
local r,err,partial = receive_ll(self, pattern, extra)
if self.rtimer then
self.rtimer:cancel()
self.rtimer = nil
end
self.reading = false
return r,err,partial
end
The -jv shows that all return statements are UCLO NYI.
But it seems that I do not use upvalues there. So what does the UCLO means
exactly?
Regards,
Jinhua Luo
