dev_GetReadWriteCid()

Retrieve the CID of the top layer of a non-multiplexed device.

#include "device.h"

LCid    dev_GetReadWriteCid
    (
        LDevice    device
    );

dev_GetReadWriteCid() retrieves the CID of the top layer of a non-multiplexed device. This give this application the ability to use standard LayGO functions to read and write on the CID.

If successful, dev_GetReadWriteCid() returns a non-negative value. Otherwise, it returns a negative value indicating the reason it failed. Possible unsuccessful return values are:

• dev_ERROR_INVALID_DEVICE
• dev_ERROR_DEVICE_NOT_OPEN
• dev_ERROR_MULTIPLEX_DEVICE
