# Error code E0092

#### Note: this error code is no longer emitted by the compiler.

An undefined atomic operation function was declared.

Erroneous code example:

    #![feature(intrinsics)]
    #![allow(internal_features)]

    #[rustc_intrinsic]
    unsafe fn atomic_foo(); // error: unrecognized atomic operation
                            //        function

Please check you didn't make a mistake in the function's name. All intrinsic functions are defined in `library/core/src/intrinsics` in the Rust source code.
