winrt::to_hresult function (C++/WinRT)

  • Article

A helper function, for use in a catch block, that turns the last exception thrown into a HRESULT error code. In a catch block that catches winrt::hresult_error, you can get an HRESULT directly from that type by using the hresult_error::to_abi member function. In other catch blocks, you can call the winrt::to_hresult function to get a HRESULT, if the exception that was thrown is any of: winrt::hresult_error, std::bad_alloc, std::out_of_range, std::invalid_argument, or std::exception.

to_hresult is a low-level function that you'll seldom need to use.

Syntax

inline __declspec(noinline) HRESULT to_hresult() noexcept;

Return value

The HRESULT error code represented by the last exception thrown.
