我如何在erlang中拆分二进制文件

我想,我想要的是相对简单的:

> Bin = <<"Hello.world.howdy?">>.
> split(Bin, ".").
[<<"Hello">>, <<"world">>, <<"howdy?">>]

有什么指针吗？

binary:split(Bin,<<".">>).

该模块二进制从EEP31(和EEP9中的溶液中加入)厄茨-5.8(见OTP-8217):

1> Bin = <<"Hello.world.howdy?">>.
<<"Hello.world.howdy?">>
2> binary:split(Bin, <<".">>, [global]).
[<<"Hello">>,<<"world">>,<<"howdy?">>]
