Question

lua io.write()写入顺序问题

tolog = function(str)
local file = io.open("log.txt","a")
str = "["..os.date().."]: "..str.."\n"
file:write(str)
end

for i = 1 ,100000000 ,1 do
if math.mod(i,1000) == 0 then
tolog(i+x)
end
end
代码，以上，输出的log.txt
[11/25/13 11:58:10]: 8000

[11/25/13 11:58:10]: 7000
[11/25/13 11:58:10]: 6000
[11/25/13 11:58:10]: 5000
[11/25/13 11:58:10]: 4000
[11/25/13 11:58:10]: 3000
[11/25/13 11:58:10]: 2000
[11/25/13 11:58:10]: 1000
[11/25/13 11:58:10]: 11000
[11/25/13 11:58:10]: 10000
[11/25/13 11:58:10]: 9000

Answer 1

tolog这个函数最后，少了一条语句：

file:close()
