Functions

__cudart_builtin__ const char * cudaGetErrorName (cudaError_t error)
Returns the string representation of an error code enum name.
__cudart_builtin__ const char * cudaGetErrorString (cudaError_t error)
Returns the description string for an error code.
__cudart_builtin__ cudaError_t cudaGetLastError (void)
Returns the last error from a runtime call.
__cudart_builtin__ cudaError_t cudaPeekAtLastError (void)
Returns the last error from a runtime call.

Detailed Description

\brief error handling functions of the CUDA runtime API (cuda_runtime_api.h)

This section describes the error handling functions of the CUDA runtime application programming interface.

Function Documentation

__cudart_builtin__ const char* cudaGetErrorName (cudaError_t error)

Returns a string containing the name of an error code in the enum. If the error code is not recognized, 'unrecognized error code' is returned.

Parameters:

error - Error code to convert to string

Returns:

char* pointer to a NULL-terminated string

cudaGetErrorString, cudaGetLastError, cudaPeekAtLastError, cudaError

__cudart_builtin__ const char* cudaGetErrorString (cudaError_t error)

Returns the description string for an error code. If the error code is not recognized, 'unrecognized error code' is returned.

Parameters:

error - Error code to convert to string

Returns:

char* pointer to a NULL-terminated string

cudaGetErrorName, cudaGetLastError, cudaPeekAtLastError, cudaError

__cudart_builtin__ cudaError_t cudaGetLastError (void)

Returns the last error that has been produced by any of the runtime calls in the same host thread and resets it to cudaSuccess.

Returns:

cudaSuccess, cudaErrorMissingConfiguration, cudaErrorMemoryAllocation, cudaErrorInitializationError, cudaErrorLaunchFailure, cudaErrorLaunchTimeout, cudaErrorLaunchOutOfResources, cudaErrorInvalidDeviceFunction, cudaErrorInvalidConfiguration, cudaErrorInvalidDevice, cudaErrorInvalidValue, cudaErrorInvalidPitchValue, cudaErrorInvalidSymbol, cudaErrorUnmapBufferObjectFailed, cudaErrorInvalidHostPointer, cudaErrorInvalidDevicePointer, cudaErrorInvalidTexture, cudaErrorInvalidTextureBinding, cudaErrorInvalidChannelDescriptor, cudaErrorInvalidMemcpyDirection, cudaErrorInvalidFilterSetting, cudaErrorInvalidNormSetting, cudaErrorUnknown, cudaErrorInvalidResourceHandle, cudaErrorInsufficientDriver, cudaErrorSetOnActiveProcess, cudaErrorStartupFailure,

Note:

Note that this function may also return error codes from previous, asynchronous launches.

__cudart_builtin__ cudaError_t cudaPeekAtLastError (void)

Returns the last error that has been produced by any of the runtime calls in the same host thread. Note that this call does not reset the error to cudaSuccess like cudaGetLastError().

Returns:

cudaSuccess, cudaErrorMissingConfiguration, cudaErrorMemoryAllocation, cudaErrorInitializationError, cudaErrorLaunchFailure, cudaErrorLaunchTimeout, cudaErrorLaunchOutOfResources, cudaErrorInvalidDeviceFunction, cudaErrorInvalidConfiguration, cudaErrorInvalidDevice, cudaErrorInvalidValue, cudaErrorInvalidPitchValue, cudaErrorInvalidSymbol, cudaErrorUnmapBufferObjectFailed, cudaErrorInvalidHostPointer, cudaErrorInvalidDevicePointer, cudaErrorInvalidTexture, cudaErrorInvalidTextureBinding, cudaErrorInvalidChannelDescriptor, cudaErrorInvalidMemcpyDirection, cudaErrorInvalidFilterSetting, cudaErrorInvalidNormSetting, cudaErrorUnknown, cudaErrorInvalidResourceHandle, cudaErrorInsufficientDriver, cudaErrorSetOnActiveProcess, cudaErrorStartupFailure,

Note:

Note that this function may also return error codes from previous, asynchronous launches.
