上面的代码先是定义bit串<<Bin>>,Value的类型默认是integer,即Bin是一个integer类型的数,然后尝试把generator产生的bit串赋值给Bin...等等,这就是bad argument的根源所在。 第二次,我们声明Bin的Value是binary类型的,所以,我们成功的接收了这个bit串。 更多关于bit串的处理,参见:http://user.it.uu.se/~pergu/...

ERL_NIF_TERM enif_make_badarg(ErlNifEnv* env) Make a badarg exception to be returned from a NIF, and associate it with the environment env. Once a NIF or any function it calls invokes enif_make_badarg, the runtime ensures that a badarg exception is raised when the NIF returns, even...
In this case, Dialyzer respects the type signature we gave, and when it analyzes the main/0 function, it figures out that there is a bad use of kind/1 in there. This prompts the warning from line 15 (number = kind({rubies, 4}),). Dialyzer from then on assumes that the type ...
