Generates the mwait instruction.

[in] a

Header file <intrin.h>

The mwait instruction is used with the monitor instruction to mark where the processor may wait for in implementation-specific event. The values of a and b are loaded into the ECX and EAX registers. For more information, see the Intel or AMD documentation as appropriate.


Some chips support the SSE3 intrinsics but do not support _mm_mwait and _mm_monitor.You should use __cpuid, __cpuidex to determine whether this intrinsic is available.

This routine is available only as an intrinsic.
