5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * Macro for checking if an I/O or MMIO emulation call succeeded.
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * This macro shall only be used with the IOM APIs where it's mentioned
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * in the return value description. And there is must be used to correctly
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * determine if the call succeeded and things like the EIP needs updating.
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * @returns Success indicator (true/false).
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * @param rc The status code. This may be evaluated
5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * more than once!

5b1d6bab9f4cf5dacf1883e7c4a40c84349f597fvboxsync * However, for efficieny we ASSUME that the
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * VINF_EM_LAST is smaller than most of the relevant
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * status codes. We also ASSUME that the
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * VINF_EM_RESCHEDULE_REM status code is the most
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * frequent status code we'll enounter in this range.
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * @todo Will have to add VINF_EM_DBG_HYPER_BREAKPOINT if the
914d33aebb63d8c288dfd1b7e74f8e2acf3eaa66vboxsync * I/O port and MMIO breakpoints should trigger before
