我的第一个erlang程序

-module(test81).
-export([start/1]).

start({N,M,Mess})->
	statistics(runtime),
	statistics(wall_clock),
	L=for(1,N,fun()->spawn(fun()->recv() end) end),
	for(1,M,fun()->lists:foreach(fun(Pid)->Pid!Mess end,L) end),
	{_,Time1}=statistics(runtime),
	{_,Time2}=statistics(wall_clock),
	U1=Time1*1000,
	U2=Time2*1000,
	io:format("~w process ~w times message cost time is:~p(~p)microseconds~n",[N,M,U1,U2]).

recv()->
	receive
	%Mess->io:format("Pid ~p recv message ~p.~n",[self(),Mess]),
	Mess->void,
	recv()
	end.

for(N,N,F)->[F()];
for(I,N,F)->[F()|for(I+1,N,F)].
