BTH_HCI_IOCTL_GET_SCO_PARAMETERS (Compact 2013)
3/26/2014
This I/O control message retrieves information about a SCO connection. Send this message with DeviceIoControl.
Syntax
BOOL DeviceIoControl(
HANDLE hDevice, // handle to device
DWORD dwIoControlCode, // use BTH_HCI_IOCTL_GET_SCO_PARAMETERS
LPVOID lpInBuffer, // pointer to input buffer
DWORD nInBufferSize, // input buffer size
LPVOID lpOutBuffer, // pointer to output buffer
DWORD nOutBufferSize, // output buffer size
LPDWORD lpBytesReturned, // number of bytes returned
OVERLAPPED lpOverlapped // pointer to OVERLAPPED structure
);
Parameters
- hDevice
The handle to the device.
- dwIoControlCode
[in] Control code for the operation. Use BTH_HCI_IOCTL_GET_SCO_PARAMETERS for this operation.
- lpInBuffer
[in] Not used; set to NULL.
- nInBufferSize
[in] Not used; set to zero.
- lpOutBuffer
[out] Points to the GetScoParameters structure that will receive the parameters; see definition below.
- nOutBufferSize
[out] Equals size of GetScoParameters.
- lpBytesReturned
- lpOverlapped
Ignored.
Remarks
You must define GetScoParameters to store data returned by this I/O control. The structure must be defined as follows.
struct {
OUT BOOL bScoSupported;
// TRUE if SCO is supported.
OUT DWORD dwScoPacketMaxDataSize;
// The maximum SCO packet size
OUT DWORD dwNumConcurrentScoPackets;
// The number of concurrent
// SCO packets, which can be outstanding.
} GetScoParameters;
