windows API 获取磁盘信息

GetLogicalDriveStrings - 获取系统中存在的逻辑驱动器字符串
GetLogicalDriveStrings(
nBufferLength: DWORD; {缓冲区大小}
lpBuffer: PAnsiChar {缓冲区}
): DWORD;

获取磁盘名称填充到lpbuffer.
GetVolumeInformation - 读取文件系统信息
GetVolumeInformation(
lpRootPathName: PChar; {磁盘驱动器代码字符串}
lpVolumeNameBuffer: PChar; {磁盘驱动器卷标名称}
nVolumeNameSize: DWORD; {磁盘驱动器卷标名称长度}
lpVolumeSerialNumber: PDWORD; {磁盘驱动器卷标序列号}
var lpMaximumComponentLength: DWORD; {系统允许的最大文件名长度}
var lpFileSystemFlags: DWORD; {文件系统标识}
lpFileSystemNameBuffer: PChar; {文件操作系统名称}
nFileSystemNameSize: DWORD {文件操作系统名称长度}
): BOOL;
GetDiskFreeSpaceEx - 获取磁盘容量信息
BOOL GetDiskFreeSpace(
LPCTSTR lpRootPathName, 
LPDWORD lpSectorsPerCluster, 
LPDWORD lpBytesPerSector,
LPDWORD lpNumberOfFreeClusters,
LPDWORD lpTotalNumberOfClusters

);
