_mm_tzcnti_32/ _mm_tzcnti

Performs an initialized trailing zero bit count. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).

Syntax

extern int __cdecl _mm_tzcnti_32(int a, unsigned int x);

extern __int64 __cdecl _mm_tzcnti_64(__int64 a, unsigned __int64 x);

`a`	integer, with 32-bit elements (for _mm_tzcnti_32) or 64-bit elements (for _mm_tzcnti_64)
`x`	unsigned integer, with 32-bit elements (for _mm_tzcnti_32) or 64-bit elements (for _mm_tzcnti_64)

Performs a trailing zero bit count operation on unsigned integer x, starting at bit a.

Returns scalar value result count operation.
