You must define GetScoParameters to store data returned by BTH_HCI_IOCTL_GET_SCO_PARAMETERS. The structure must be defined as follows.
struct {
OUT BOOL bScoSupported; // Determines if SCO is supported.
OUT DWORD dwScoPacketMaxDataSize; // Stores the maximum SCO packet size
OUT DWORD dwNumConcurrentScoPackets; // Stores the number of concurrent
//SCO packets, which can be
//outstanding.
} GetScoParameters;
