<12>简述erlang的几种错误

1)  badarg Bad argument. The argument is of wrong data type, or is otherwise badly formed.
参数错误，例如
erlang:exit(aa, zz).

2)  badarith Bad argument in an arithmetic expression.
数字匹配错误，例如
2+a.

3)
{badmatch,V} Evaluation of a match expression failed. The value V did not match.
1> A = 3.
3
2> A = 4.
** exited: {{badmatch,4},[{erl_eval,expr,3}]} **
在我的shell中是这样
5> A = 3.
3
6> A = 4.
** exception error: no match of right hand side value 4

4)
function_clause No matching function clause is found when evaluating a function call.
没有匹配的函数
在文件test.erl 58,59行
58 t3(a) ->
59     {ok, t3}.

test:t3(b).
** exception error: no function clause matching test:t3(b) (test.erl, line 58)


5）
noproc Trying to link to a non-existing process.

6）
undef The function cannot be found when evaluating a function call.
