NAME¶

std::set_unexpected - std::set_unexpected

Synopsis¶

Defined in header <exception>
std::unexpected_handler set_unexpected( std::unexpected_handler (until C++11)
f ) throw();
std::unexpected_handler set_unexpected( std::unexpected_handler (since C++11)
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 (since C++11)
std::set_unexpected and std::get_unexpected

Parameters¶

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.
