# 1.27.0[−][src]Function core::arch::x86::_mm_cmpistra

    pub unsafe fn _mm_cmpistra(a: __m128i, b: __m128i, imm8: i32) -> i32

This is supported on x86 and target feature `sse4.2` only.

Compares packed strings with implicit lengths in `a` and `b` using the control in `imm8`, and return `1` if `b` did not contain a null character and the resulting mask was zero, and `0` otherwise.
