Generates the mwait instruction.
void _mm_mwait( unsigned int a, unsigned int b, );
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.
