使用C++对磁盘进行检测获取磁盘相应的信息

1、使用c+对磁盘进行检测，获取磁盘相应的信息tern "c" _decpec(dll)int getlogicdiskinfo() int dtype; int si = 0; bool relt; unsign _int64 i64freebytestocaller; unsigned _int64 i64totalbytes; unsigned _int64 i64freebytes; float totalsize;/总空间 float usablesize;/可用空间 int dslength = getlogicaldrivesings(0,null);/通过该函数

2、猎取全部驱动器字符串信息长度 cout "长度为：" dslength endl; ofstream in;/向文件写内容 in.open("d:diskinfo.txt",ios:tru);/ios:trunc表示在打开文件前将文件清空，因为是写入操作，当文件不存在则创建 char* dstr = new chardslength; getlogicaldrivestrings(dslength,(lptstr)dstr); for(int i=0;i dslength/4;+i) char dir3 = dstrsi,':','

3、;' /cout "磁盘名称为：" dir0 dir1 dir2 endl; in "磁盘名称为：" dir0 dir1 dir2 "n" char str3 = 0,0,0; str0 = dir0; str1 = dir1; string dirname = str; dtype = getdrivetype(lptstr)dstr+i*4);/通过该函数猎取磁盘的类型 string drivertype; if(dtype = drive_fixed) drivertype = "本地磁盘" /cou

4、t drivertype endl; in "磁盘类型为：" drivertype "n" else if(dtype = drive_cdrom) drivertype = "光驱" /cout drivertype endl; in "磁盘类型为：" drivertype "n" else if(dtype = drive_removable) drivertype = "可移动磁盘" /cout drivertype endl; in "磁盘类型为："

5、; drivertype "n" else if(dtype = drive_remote) drivertype = "网络磁盘" /cout drivertype endl; in "磁盘类型为：" drivertype "n" else if(dtype = drive_ramdisk) drivertype = "虚拟ram磁盘" /cout drivertype endl; in "磁盘类型为：" drivertype "n" else if(d

6、type = drive_unknown) drivertype = "未知设备" /cout drivertype endl; in "磁盘类型为：" drivertype "n" if(dirname = "c:")/当磁盘为c盘时 result = getdiskfreespaceex(_t("c:"),(pularge_integer) i64freebytestocaller,(pularge_integer) i64totalbytes,(pularge_integer) i64fr

7、eebytes);/猎取磁盘的空间状态 if(result) totalsize = (float)i64totalbytes/1024/1024/1024; usablesize = (float)i64freebytestocaller/1024/1024/1024; /cout "总空间为：" totalsize "gb" endl; /cout "可用空间为：" usablesize "gb" endl; /cout "=" endl; in "总空间为：" tota

8、lsize "gb" "n" in "可用空间为：" usablesize "gb" "n" in "=" "n" else /cout "未检测到磁盘设备" endl; in "未检测到磁盘设备" "n" else if(dirname = "d:")/当磁盘为d盘时 result = getdiskfreespaceex(_t("d:"),(pularg

9、e_integer) i64freebytestocaller,(pularge_integer) i64totalbytes,(pularge_integer) i64freebytes);/猎取磁盘的空间状态 if(result) totalsize = (float)i64totalbytes/1024/1024/1024; usablesize = (float)i64freebytestocaller/1024/1024/1024; /cout "总空间为：" totalsize "gb" endl; /cout "可用空间为：&qu

10、ot; usablesize "gb" endl; /cout "=" endl; in "总空间为：" totalsize "gb" "n" in "可用空间为：" usablesize "gb" "n" in "=" "n" else /cout "未检测到磁盘设备" endl; in "未检测到磁盘设备" "n" else if(d

11、irname = "e:")/当磁盘为e盘时 result = getdiskfreespaceex(_t("e:"),(pularge_integer) i64freebytestocaller,(pularge_integer) i64totalbytes,(pularge_integer) i64freebytes);/猎取磁盘的空间状态 if(result) totalsize = (float)i64totalbytes/1024/1024/1024; usablesize = (float)i64freebytestocaller/1024/

12、1024/1024; /cout "总空间为：" totalsize "gb" endl; /cout "可用空间为：" usablesize "gb" endl; /cout "=" endl; in "总空间为：" totalsize "gb" "n" in "可用空间为：" usablesize "gb" "n" in "=" "n"

13、; else /cout "未检测到磁盘设备" endl; in "未检测到磁盘设备" "n" else if(dirname = "f:")/当磁盘为f盘时 result = getdiskfreespaceex(_t("f:"),(pularge_integer) i64freebytestocaller,(pularge_integer) i64totalbytes,(pularge_integer) i64freebytes);/猎取磁盘的空间状态 if(result) totalsiz

14、e = (float)i64totalbytes/1024/1024/1024; usablesize = (float)i64freebytestocaller/1024/1024/1024; /cout "总空间为：" totalsize "gb" endl; /cout "可用空间为：" usablesize "gb" endl; /cout "=" endl; in "总空间为：" totalsize "gb" "n" in &

15、quot;可用空间为：" usablesize "gb" "n" in "=" "n" else /cout "未检测到磁盘设备" endl; in "未检测到磁盘设备" "n" else if(dirname = "g:")/当磁盘为e盘时 result = getdiskfreespaceex(_t("g:"),(pularge_integer) i64freebytestocaller,(pularg

16、e_integer) i64totalbytes,(pularge_integer) i64freebytes);/猎取磁盘的空间状态 if(result) totalsize = (float)i64totalbytes/1024/1024/1024; usablesize = (float)i64freebytestocaller/1024/1024/1024; /cout "总空间为：" totalsize "gb" endl; /cout "可用空间为：" usablesize "gb" endl; /co

17、ut "=" endl; in "总空间为：" totalsize "gb" "n" in "可用空间为：" usablesize "gb" "n" in "=" "n" else /cout "未检测到磁盘设备" endl; in "未检测到磁盘设备" "n" si+=8; in.close();/关闭文件 if(null != dtype) return

18、 dtype; else return -1; 该代码主要用来猎取磁盘的盘符、磁盘的类型、磁盘的总空间大小以及磁盘的可用空间大小。 public ic map string, returnpo getdiscinfo() string dirname = "d:disk" string name = "info.txt" string disknamestr = "磁盘名称" string disktypestr = "磁盘类型" string totalsizestr = "总空间" stri

19、ng usablesizestr = "可用空间" string diskname = null; string disktype = null; float totalsize = 0; float usablesize = 0; map string, returnpo map = new hashmap string, returnpo returnpo returnpo = new returnpo(); list usbpo list = new arraylist usbpo usbpo usbpo = null; jnative jnative = null;

20、 try jnative = new jnative("pcsuite", "getlogicdiskinfo");/ 加载pcsuite.dll文件 jnative.retval(type.int); / jnative.invoke(); file file = new file(dirname + filename);/ 实例化文件对象，读取一个放置于本地磁盘中存放磁盘信息的文件 if (file.exists() bufferedreader br = new bufferedreader(new filereader(file); string
