Information on the Variable Types Where do you get the information


I have been trying to use CUDA being called from a Fortran program which is so far going ok. I am however having problems in finding information on the various variable types within CUDA. I found the Fortran examples on the nVidia website which made use of the cuComplex variable type so I went looking for some documentation on what other types there are available. Sadly I have been unsuccessful in my search. I tried all the files in the Documentation section of the website but found no reference to cuComplex. Does anyone have any suggestions where to look?
