std::get_unexpected

STD：得到[医]意料之外

Defined in header ​​
std::unexpected_handler get_unexpected(​(until C++17) (since c++11, deprecated in C++11)

返回当前安装的std::unexpected_handler，它可能是空指针。

This function is thread-safe. Prior call to std::set_unexpected synchronizes-with (see std::memory_order) the subsequent calls to this function.(since C++11)

参数

%280%29

返回值

当前安装的std::unexpected_handler...

例外

noexcept规格：

noexcept

另见

unexpected_handler (until C++17)the type of the function called by std::unexpected (typedef)
set_unexpected (until C++17)changes the function to be called by std::unexpected (function)
