RtgvGetLastStreamError

RtgvGetLastStreamError gets the last error that occurred in the stream associated with the specified camera.

Syntax

BOOL RtgvGetLastStreamError(
    [in]    UINT32 cameraHandle, 
    [out]   PDWORD pError
);

Parameters

[in] cameraHandle

The handle to the camera whose stream encountered an error.

[out] pError

A pointer to a DWORD that receives the error.

Return Values

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. Call GetLastError to obtain an error code.

Remarks

This function will fail if it is called before RtgvInitialize and RtgvInitCameraControl.

To find the camera to query, call RtgvInitialize and then call RtgvEnumerateCameras to get an RTGV_CAMERA_INFO array describing each camera found on the network, along with its handles.
