Function ulock_sys::weak::ulock_wake

pub unsafe fn ulock_wake(
    op: u32, 
    addr: *mut c_void, 
    val: u64
) -> Result<c_int, ApiUnsupported>

Equivalent to __ulock_wake, but lazy-loads and returns Err(ApiUnsupported) if this machine doesn't support the API.

It's generally faster to call this than to call ULockApi::get()?.ulock_wake(...) unless you can cache the result of get somewhere easy.

Safety

Same as __ulock_wake
