Function Documentation

NVCVStatus nvcvGetLastErrorMessage(char *msgBuffer, int32_t lenBuffer)

Returns and resets the error status code and message of the last CV-CUDA function call that failed in current thread.

A new call to this function will return NVCV_SUCCESS, as the thread-specific status was reset. This operation doesn’t affect the status in other threads.

It’s guaranteed that the message is never larger than NVCV_MAX_STATUS_MESSAGE_LENGTH bytes, including the ‘\0’ string terminator.

Parameters:

• msgBuffer – [out] Pointer to memory where the status message will be written to. If NULL, no message is returned.

• lenBuffer – [in] Size in bytes of msgBuffer.

  • If less than zero, lenBuffer is assumed to be 0.

Returns:

The status of the last CV-CUDA function call that failed in current thread.
