Functions

const __cudart_builtin__ char* cudaGetErrorString ( cudaError_t error )

Returns the message string from an error code.

Parameters

error

- Error code to convert to string

Returns

char* pointer to a NULL-terminated string

Description

Returns the message string from an error code.

cudaError_t cudaGetLastError ( void )

Returns the last error from a runtime call.

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,

Description

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

Note:

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

cudaError_t cudaPeekAtLastError ( void )

Returns the last error from a runtime call.

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,

Description

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().

Note:

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