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

    pub unsafe fn _mm_cmpestrc(
        a: __m128i,
        la: i32,
        b: __m128i,
        lb: i32,
        imm8: i32
    ) -> i32

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

Compare packed strings in `a` and `b` with lengths `la` and `lb` using the control in `imm8`, and return `1` if the resulting mask was non-zero, and `0` otherwise.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
