[webkit-help] How to get a C String from a WebCore::String

[n179911]

Hi,

Can you please tell me how can I get a C String from a WebCore::String?
I tried "c_str" method, but It said
error: 'class WebCore::String' has no member named 'c_str'

And I tried looking for WebCore::String .h file? The closest I can
find is webkit/api/public/WebString.h? Can you please tell me how can
i find all the public methods of WebCore::String?

Thank you.
