cufftcomplex.h Programmers reference/Documentation

I am working on an cufft implementation and can't find any reference to the cufftcomplex functions. I found cucomplex.h through google, though, but that doesn't help me. Specifically i want to know, how to read out the imaginary part and the real part of the cufftcomplex struct.

The types cufftComplex and cuComplex are actually same. It is documented in the cuFFT documentation. In cufft.h you will find the typedef:

typedef cuComplex cufftComplex;

In cuComplex.h you will find that cuComplex is indeed a float2, i.e. you can read out the real value with c.x and the imaginary value with c.y. Or better use the functions cuCrealf() and cuCimagf() which are provided in cuComplex.h.
