class cuda_exception : public std::exception

Exception type across CUDA, CUBLAS, and CUSOLVER.

Public Functions

cuda_exception() = delete

template<typename T>
inline cuda_exception(

const T status,

const ::cuda::std::source_location loc = ::cuda::std::source_location::current(),

)

Constructs an exception object from a status value.

If status is 0, the exception is still created with an empty error message. Otherwise, the constructor initializes the error message (later accessible with what()) appropriately.

Template Parameters:

T – status type, can be cudaError_t, cublasStatus_t, or cusolverStatus_t

Parameters:

• status – status value, usually the result of a CUDA API call

• loc – location of the call, defaulted

inline const char *what() const noexcept override

Returns a message describing the error.

Returns:

the error message
