6.13. Error Handling

This section describes the error handling functions of the low-level CUDA driver application programming interface.

Functions

CUresult cuGetErrorName(CUresult error, const char **pStr)

Gets the string representation of an error code enum name.

CUresult cuGetErrorString(CUresult error, const char **pStr)

Gets the string description of an error code.

6.13.1. Functions

CUresult cuGetErrorName(CUresult error, const char **pStr)

Gets the string representation of an error code enum name.

Sets *pStr to the address of a NULL-terminated string representation of the name of the enum error code error. If the error code is not recognized, CUDA_ERROR_INVALID_VALUE will be returned and *pStr will be set to the NULL address.

Parameters

  • error – - Error code to convert to string

  • pStr – - Address of the string pointer.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE

CUresult cuGetErrorString(CUresult error, const char **pStr)

Gets the string description of an error code.

Sets *pStr to the address of a NULL-terminated string description of the error code error. If the error code is not recognized, CUDA_ERROR_INVALID_VALUE will be returned and *pStr will be set to the NULL address.
