How to include api classes

[kidd106]

How would I include a api class in a program. I'm assuming that I would need to include a header file. After that I assume that I would would just create a new object of the included class.

If my assumptions are correct, how do I know which header files to include? Say I wanted to use the BStopWatch class http://api.haiku-os.org/classBStopWatch.html

For working with an API you need to read up on that API's documentation, the includes and compiler flags and so on should be there.
