_mm_minpos_epu16

Microsoft Specific

Emits the Streaming SIMD Extensions 4 (SSE4) instruction phminposuw. This instruction selects the minimum from a set.


__m128i _mm_minpos_epu16( 
   __m128i a
);

[in] a

A 128-bit parameter that contains eight 16-bit unsigned integers.

A 128-bit value. The lowest order 16 bits are the minimum value found in parameter a. The second-lowest order 16 bits are the index of the minimum value found in parameter a.
