Why is all of this faster than just calling strcmp. Isnt it doing similar internally more optimized?

I think we just call it callback and not CallBack. But please check

There are API tests testing these things?

I think it is OK to use url both places and have url(url). I am pretty sure that works in C++

if (!str || !m_string)
    return str == m_string;

Not needed anymore

I don't think this is needed. This does not seem faster since it needs to iterate.

I think we still need the NULL case check before strcmp(), right?

It is supposed to work on null terminated strings, so I am not sure. At least it is worth checking the implementation.

http://sourceware.org/git/?p=glibc.git;a=blob;f=string/strcmp.c;

There is no checking for NULL

Not explicitly, but it is used in /Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_download_job.cpp
