std::set_unexpected - cppreference.com (original) (raw)

| Defined in header | | | | ------------------------------------------------------------------------------------------------------------------------------------------ | | ---------------------------------------- | | std::unexpected_handler set_unexpected( std::unexpected_handler f ) throw(); | | (until C++11) | | std::unexpected_handler set_unexpected( std::unexpected_handler f ) noexcept; | | (deprecated in C++11) (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)

[edit] Parameters

[edit] Return value

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