CUDA Driver API :: CUDA Toolkit Documentation

4.3. Initialization

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

Functions

CUresult cuInit ( unsigned int Flags ): Initialize the CUDA driver API.

Functions

CUresult cuInit ( unsigned int Flags )

Initialize the CUDA driver API.

Parameters

Flags: - Initialization flag for CUDA.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_DEVICE

Description

Initializes the driver API and must be called before any other function from the driver API. Currently, the Flags parameter must be 0. If cuInit() has not been called, any function from the driver API will return CUDA_ERROR_NOT_INITIALIZED.

Note:

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