std::set_unexpected: std::set_unexpected


std::set_unexpected - std::set_unexpected


Defined in header <exception>
std::unexpected_handler set_unexpected( std::unexpected_handler f ) throw(); (until C++11)
                                                                               (since C++11)
std::unexpected_handler set_unexpected( std::unexpected_handler f ) noexcept; (deprecated)
                                                                               (removed in C++17)

Makes f the new global std::unexpected_handler and returns the previously installed 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)


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

Return value

The previously-installed unexpected handler, or a null pointer value if none was installed.
