RtgvGetFrameWidth

RtgvGetFrameWidth gets the currently configured frame width of a camera.

Syntax

BOOL RtgvGetFrameWidth(
    [in]    HANDLE cameraHandle, 
    [out]   PUINT32 pWidth
);

Parameters

[in] cameraHandle

The handle of the camera being queried.

[out] pWidth

A pointer to an unsigned integer that receives the currently configured frame width, in pixels, of the camera specified by cameraHandle.

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.
