获取PC参数信息

1 获取系统主机名称：

WORD   wVersionRequested; 

 WSADATA   wsaData; 

 

 wVersionRequested = MAKEWORD(2,0); 

 

 WSAStartup(wVersionRequested, &wsaData); //加载Winsock库

 

 char   szHostName[128] = {0}; 

 if (gethostname(szHostName, 256) == 0)

 {

        printf("%s\n",szHostName);

 }

 

 WSACleanup(); //注销

 

2. 获取内存大小

MEMORYSTATUS memoryStatus;

 memset (&memoryStatus, 0, sizeof(MEMORYSTATUS));

 memoryStatus.dwLength = sizeof (MEMORYSTATUS);

 GlobalMemoryStatus (&memoryStatus);

 printf("内存总大小为：%d Mb", memoryStatus.dwTotalPhys/(1024*1024));

 printf(" 内存可用大小为：%d Mb",memoryStatus.dwAvailPhys/(1024*1024));

 

3.获取磁盘信息：

  ULONGLONG nTotalBytes = 0, nFreeBytes = 0;

  if(GetDiskSpaceInfo(“C:\\”, nTotalBytes, nFreeBytes))

  {

      printf("C盘总大小：%.2f Gb", (double)nTotalBytes/(1024*1024*1024));

      printf("C盘可用空间：%.2f Gb", (double)nFreeBytes/(1024*1024*1024));

 }
