可以使用 Windows  API 来获取网络接口的 IP 地址。比如，可以使用GetAdaptersInfo方法来获取 IP 地址。

下面的代码示例演示如何使用 GetAdaptersInfo 方法来获取 Windows 网络接口的 IP 地址：

// System Headers 
#include <windows.h> 
#include <winsock2.h> 
#include <ws2tcpip.h>
#include <stdio.h>	
#include <iphlpapi.h>

//lib 
#pragma comment(lib, "IPHLPAPI.lib") 

// prototype 
int GetNetworkAdaptersIP();

// main 
int main() 
{
	int iResult;
	iResult = GetNetworkAdaptersIP();
	printf("GetNetworkAdaptersIP returned : %d \n", iResult);
	return 0; 
}

int GetNetworkAdaptersIP() 
{
	// buffer 
	PIP_ADAPTER_ADDRESSES pAdapterAddresses = NULL; 
	ULONG ulOutBufLen = 0;

	// getting required buffer size 
	DWORD dwRetVal = 0;
	dwRetVal = GetAdaptersAddresses(AF_UNSPEC, GAA_FLAG_INCLUDE_PREFIX, NULL, pAdapterAddresses, &ulOutBufLen);

	if (dwRetVal == ERROR_BUFFER_OVERFLOW) 
	{
		// allocation buffer 
		pAdapterAddresses = (IP_ADAPTER_ADDRESSES *)malloc(ulOutBufLen);

		// getting adapter IPs 
		dwRetVal = GetAdaptersAddresses(AF_UNSPEC,GAA_FLAG_INCLUDE_PREFIX, NULL, pAdapterAddresses, &ulOutBufLen); 
		if (dwRetVal == NO_ERROR)
		{
			PIP_ADAPTER_ADDRESSES pCurrentAddress = pAdapterAddress;
			while (pCurrentAddress) 
			{
				PIP_ADAPTER_UNICAST_ADDRESS pUnicastAddress = pCurrentAddress->FirstUnicastAddress;
				if (pUnicastAddress) 
				{
					SOCKET_ADDRESS SocketAddress = pUnicastAddress->Address;
					struct sockaddr_in *sin = (struct sockaddr_in*)SocketAddress.lpSockaddr;
					char* ip = inet_ntoa(sin->sin_addr);
					printf("IP Address: %s\n", ip);
				}
				pCurrentAddress = pCurrentAddress->Next;
			}
		}
		else 
		{
			// error handling 
			printf("GetAdaptersAddresses failed with error: %d\n", dwRetVal);
			if (pAdapterAddresses) 
				free(pAdapterAddresses);
			return 1; 
		}

		// freeing buffer 
		if (pAdapterAddresses) 
			free(pAdapterAddresses);
		return 0;
	} 
	else 
	{
		// error handling 
		printf("GetAdaptersAddresses failed with error: %d\n", dwRetVal);
		if (pAdapterAddresses) 
			free(pAdapterAddresses);
		return 1; 
	}
}
