std::set_unexpected

STD：设置[医]意料之外

Defined in header ​​
std::unexpected_handler set_unexpected( std::unexpected_handler f ​(until C++17) (deprecated since C++11)

制造f新的全球std::unexpected_handler并返回先前安装的std::unexpected_handler...

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

参数

f-pointer to function of type std::unexpected_handler, or null pointer

返回值

以前安装的意外处理程序，如果没有安装，则为空指针值。

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

另见

unexpected (until C++17)function called when dynamic exception specification is violated (function)
get_unexpected (C++11)(until C++17)obtains the current unexpected_handler (function)
unexpected_handler (until C++17)the type of the function called by std::unexpected (typedef)
