FindNextFTPDevice
Get the next searched device position information.
DWORD
FindNextFTPDevice
{
DWORD *
dwPos
,
LPTSTR
szDeviceName
,
ULONGLONG *
btAddress
,
int
nNameLen
}
Parameters
dwPos
[in/out] a reference to a position value returned by
FindFirstBTDevice
or
FindNextBTDevice
function
szDeviceName
[out] The buffer to receive the device name string
btAddress
[out] Receive the device address of 64-bit unsigned integer
nNameLen
[in] The
szDeviceName
buffer max size. If terminal device name length > nNameLen, the
szDeviceName
buffer store data of nNameLen length
Returned Values
If the action succeeds, the returned value is
E_FUNC_SUCCEED
. If the action fails, possible returned values are
E_FUNC_ERROR
,
E_FUNC_PAR_ERROR
,
BT_ERR_DEVICE_ERROR
.
Example
#define GET_NAP(_bt_addr) ( (USHORT) (((_bt_addr) & (ULONGLONG)0xFFFF00000000) >> (8*4)) )
#define GET_SAP(_bt_addr) ( (ULONG) (((_bt_addr) & (ULONGLONG)0x0000FFFFFFFF) >> (0)) )
DWORD dwPos, dwRe;
WCHAR szDeviceName[128], szAddress[16];
ULONGLONG btAddress;
If(InitSearchFTPDevice() == E_FUNC_SUCCEED){
dwRe = FindFirstFTPDevice(&dwPos, szDeviceName, & btAddress, 256);
while(dwRe == E_FUNC_SUCCEED){
FindNextFPTDevice(&dwPos, szDeviceName, & btAddress, 256);
if(dwRe != E_FUNC_SUCCEED)
break;
