可以尝试将代码中的WSAQUERYSET result改为LPWSAQUERYSET result,即使用指向WSAQUERYSET结构体的指针类型,代码如下:
int main() {
std::map<std::string, std::string> config = readIniFile("config.ini");
int bluetoothCount = std::stoi(config["bluetooth.count"]);
std::string logFileName = config["log.filename"];
WSADATA wsaData;
int iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (iResult != 0) {
std::cout << "WSAStartup failed: " << iResult << std::endl;
return 1;
}
WSAQUERYSET service;
memset(&service, 0, sizeof(service));
service.dwSize = sizeof(service);
service.dwNameSpace = NS_BTH;
HANDLE lookupHandle = NULL;
iResult = WSALookupServiceBegin(&service, LUP_CONTAINERS, &lookupHandle);
if (iResult != 0) {
std::cout << "WSALookupServiceBegin failed: " << iResult << std::endl;
WSACleanup();
return 1;
}
int count = 0;
while (count < bluetoothCount) {
WSAQUERYSET* result;
memset(&result, 0, sizeof(result));
result->dwSize = sizeof(WSAQUERYSET);
iResult = WSALookupServiceNext(lookupHandle, LUP_RETURN_NAME | LUP_RETURN_ADDR, result);
if (iResult != 0) {
break;
}
count++;
}
WSALookupServiceEnd(lookupHandle);
WSACleanup();
if (count >= bluetoothCount) {
std::string logText = "Bluetooth count is " + std::to_string(count) + ", reached the target count of " + std::to_string(bluetoothCount);
writeLogFile(logFileName, logText);
}
else {
std::string logText = "Bluetooth count is " + std::to_string(count) + ", did not reach the target count of " + std::to_string(bluetoothCount);
writeLogFile(logFileName, logText);
}
return 0;
}
