1. getvolumeinformation function declaration

Bool getvolumeinformation (lpctstr lprootpathname, lptstr kernel, DWORD kernel, lpdword kernel, lpdword lpmaximum componentlength, lpdword lpfilesystemflags, lptstr lpfilesystemnamebuffer, DWORD nfilesystemnamesize)

Lprootpathname: disk symbol with the root directory identifier.

Lpvolumenamebuffer: The volume name buffer.

Nvolumenamesize: the buffer size of the volume name.

Lpvolumeserialnumber: disk serial number.

Lpmaximum componentlength: Maximum File Name Length.

Lpfilesystemflags: indicates the compressed disk.

Lpfilesystemnamebuffer: File System name buffer.

Nfilesystemnamesize: the buffer size of the file system name.

Function: obtains information about a disk volume. True is returned if the call succeeds. False is returned if the call fails.
