hipError_t hipGLGetDevices(unsigned int *pHipDeviceCount, int *pHipDevices, unsigned int hipDeviceCount, hipGLDeviceList deviceList)#

Queries devices associated with the current OpenGL context.

Parameters:

  • pHipDeviceCount – [out] - Pointer of number of devices on the current GL context.

  • pHipDevices – [out] - Pointer of devices on the current OpenGL context.

  • hipDeviceCount – [in] - Size of device.

  • deviceList – [in] - The setting of devices. It could be either hipGLDeviceListCurrentFrame for the devices used to render the current frame, or hipGLDeviceListAll for all devices. The default setting is Invalid deviceList value.

Returns:

hipSuccess, hipErrorInvalidValue, hipErrorNotSupported

hipError_t hipGraphicsGLRegisterBuffer(hipGraphicsResource **resource, GLuint buffer, unsigned int flags)#

Registers a GL Buffer for interop and returns corresponding graphics resource.

Parameters:

  • resource – [out] - Returns pointer of graphics resource.

  • buffer – [in] - Buffer to be registered.

  • flags – [in] - Register flags.

Returns:

hipSuccess, hipErrorInvalidValue, hipErrorUnknown, hipErrorInvalidResourceHandle

hipError_t hipGraphicsGLRegisterImage(hipGraphicsResource **resource, GLuint image, GLenum target, unsigned int flags)#

Register a GL Image for interop and returns the corresponding graphic resource.

Parameters:

  • resource – [out] - Returns pointer of graphics resource.

  • image – [in] - Image to be registered.

  • target – [in] - Valid target value Id.

  • flags – [in] - Register flags.

Returns:

hipSuccess, hipErrorInvalidValue, hipErrorUnknown, hipErrorInvalidResourceHandle
