About the "cudaError_t"

Accelerated Computing CUDA CUDA Programming and Performance

Hi everybody here.
Does anybody know where is “cudaError_t” defined.
I couldn’t find anywhere.
I have searched all the include header file *.h.
by the way. I get an error number is “6”.
so I don’t know what does error mean.
thank you very much. :)

struct cudaError_t is defined at “driver_types.h” in “include” directory under your cuda toolkit installed directory.

I’ll show you contents related with cudaError_t.
