Unreal have done something horrible to their documentation home page.
To search the C++ API documentation, start here:
Do you know of anyway for the search on that page to be limited to the C++ API? Its frustrating to have to select that subheading after every search.
Oh hey! I just checked out the address line when searching and it is doing a live search with the C++ API as a filter. If there was a way to force that on to the end of any search in the search field (Chrome customization?) that would help.
But for now I edited the address so the search term is last like this:
https://www.unrealengine.com/en-US/bing-search?offset=0&filter=C%2B%2B%20API&keyword=UClass
that way I can just change the last term to what I am looking for and it will come up in the C++ api!!!
