Hi,
I need to know all the hark disks of my computer and also any removable device available. Is for a 3D interface, I can't use any the standard dialogs.
Any helps is more than welcome.
How can I know the hard disk of my computer?
For windows You can use
#define DRIVE_UNKNOWN 0
#define DRIVE_NO_ROOT_DIR 1
#define DRIVE_REMOVABLE 2
#define DRIVE_FIXED 3
#define DRIVE_REMOTE 4
#define DRIVE_CDROM 5
#define DRIVE_RAMDISK 6
WINBASEAPI
DWORD
WINAPI
GetLogicalDrives(
VOID
);
WINBASEAPI
UINT
WINAPI
GetDriveTypeA(
__in_opt LPCSTR lpRootPathName
);
WINBASEAPI
UINT
WINAPI
GetDriveTypeW(
__in_opt LPCWSTR lpRootPathName
);
#ifdef UNICODE
#define GetDriveType GetDriveTypeW
#else
#define GetDriveType GetDriveTypeA
#endif // !UNICODE
You must use it like:
for( char ch = 'A' ; ch <= 'Z' ; ++ch )
...
For linux maybe you must manually read /etc/fstab, or use <fstab.h>
#define DRIVE_UNKNOWN 0
#define DRIVE_NO_ROOT_DIR 1
#define DRIVE_REMOVABLE 2
#define DRIVE_FIXED 3
#define DRIVE_REMOTE 4

Maybe no, that's internal wxWidgets function for wxGenericDirCtrl:
