Equality of 2 byte arrays/inline c array

I'm programming in objective-c so I can use C as well. I have an array of bytes: (eg)

Byte byteArray[] = {0,0};

And I need to compared to another array which is hard coded. So I'm looking to do something like:

if (byteArray == {0,1}) {
    //do something
}

But there is the erro开发者_如何学Gor "Expected Expression" on the curly braces. Is it not possible to have an inline C array?

byte toTest[2] = {0, 1};
if(memcmp(byteArray, toTest, sizeof(toTest)) == 0) { ... }

Or the easier way:

if(byteArray[0] == 0 && byteArray[1] == 1) { ... }

Even if the array wouldn't be "inline" you couldn't do that, because the rvalue of an array is its memory address.

You need to use memcmp.

You can use mempcmp():

Byte otherArray[] = {0, 1};
if (memcmp(byteArray, otherArray, sizeof(byteArray)) == 0) {
    // ... equal
}

If you have C99 support, you could also use something like:

memcmp(byteArray, &(Byte[]){0,1}, 2)

... but in my opinion that get's quickly unreadable.
