mode
a pointer to MODE2255 structure containing the desired operation mode (see s2255.h).
Returns

S2255_RegBuffer(HANDLE hdev, int channel, BUFFER *pBuf, UINT32 size);
Registers a buffer for a specific device/channel combination. The image buffers have to be
allocated by the application software. The 2255 driver fills in the buffers with image data.
Parameters
hdev
A handle to the 2255 device.
channel
channel number (1-4).
pBuf
a pointer to BUFFER structure (see s2255.h).
size
requested buffer size.
Returns
0 on success.
S2255_DqBuf(HANDLE hdev, int channel, int frmnum);
Informs the driver that the application is releasing a frame back to the driver. Failure to do that
may cause the driver to skip frames because of “buffer starvation”.
Parameters
hdev
A handle to the 2255 device.
channel
