在erlang中用文件写一个元组

Question

How to write a tuple in file in erlang.What i have tried so far is

Result={1,"OK",3},
file:write_file("/tmp/logs.txt", Result, [append])

But it is giving bad args error. Any solutions??

Answer 1

file:write_file takes an iolist, not a plain Erlang term. You could format the term as an iolist using io_lib:format :

file:write_file("/tmp/logs.txt", io_lib:format("~p.~n", [Result]), [append])
