std::basic_ios::exceptions

性病：基本[医]监督办：例外情况

std::ios_base::iostate exceptions() const;(1)​
void exceptions( std::ios_base::iostate except (2)​

获取并设置流的异常掩码。异常掩码确定错误状态，在出现错误状态时，流抛出类型的异常。failure...

1%29返回异常掩码。

2%29将异常掩码设置为except...

参数

except-exception mask

返回值

1%29当前异常掩码。

2%29%280%29

注记

例

二次

#include <iostream>
#include <fstream>
 
int main() 
{
    int ivalue;
    try {
        std::ifstream in("in.txt"
        in.exceptions(std::ifstream::failbit
        in >> ivalue;
    } catch (std::ios_base::failure &fail) {
        // handle exception here
    }
}
