win mobile 启蓝牙 以及 重启系统 的API函数是什么？

可以动态调用bthutil.Dll中的BthSetMode函数来找开启蓝牙

C/C++ code [code]enum BTH_RADIO_MODE
{
BTH_POWER_OFF,
BTH_CONNECTABLE,
BTH_DISCOVERABLE
};

typedef int(*pBthSetMode)(DWORD);
typedef int(*pBthGetMode)(DWORD*);

HINSTANCE  hModule = LoadLibrary (L"bthutil.Dll");
if(hModule != NULL)
{
pBthSetMode BthSetMode = (pBthSetMode) GetProcAddress(hModule, _T("BthSetMode"));
pBthGetMode BthGetMode = (pBthGetMode) GetProcAddress(hModule, _T("BthGetMode"));
if(BthSetMode != NULL && BthGetMode != NULL)
{
DWORD dwMode;
int nRet = BthGetMode(&dwMode);
if (dwMode == BTH_POWER_OFF || dwMode == BTH_CONNECTABLE)
{
BthSetMode(BTH_DISCOVERABLE);
FreeLibrary(hModule);
return TRUE;
}
}
FreeLibrary(hModule);

蓝牙有三种状态：
1.关闭，BTH_POWER_OFF
2.开启，不可见 BTH_CONNECTABLE
3.开启，可见 BTH_DISCOVERABLE

获取蓝牙当前模式调用函数：
int BthGetMode(DWORD *dwMode);
其中dwMode保存了蓝牙状态参数BTH_POWER_OFF，BTH_CONNECTABLE，BTH_DISCOVERABLE中的一个

设置蓝牙状态调用函数：int BthSetMode（DWORD dwMode);
比如开启蓝牙 BthSetMode(BTHCONNECTABLE);
}
return FALSE;
