Functions ¶
func GetVolumeInformationByHandle ¶
func GetVolumeInformationByHandle(handle syscall.Handle) (volumeLabel string, serialNumber uint32, maxComponentLength uint32, flags uint32, fileSystem string, err error)
GetVolumeInformationByHandle retrieves information about the volume represented by the given system handle.
func GetVolumeNameForVolumeMountPoint ¶
GetVolumeNameForVolumeMountPoint retrieves the first volume name for the given mount point, which is a path in one of the following forms:
X:\ Y:\MountX\
Volume names are also known as volume GUID paths, and are based on the globally unique identifier of the volume. Volume names are not supplied by or editable by users, unlike volume labels.
Volume names will always be of this form:
\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\
func GetVolumePathNamesForVolumeName ¶
GetVolumePathNamesForVolumeName returns a complete set of volume paths and mount points for the given volume name, which must be a volume GUID path of this form:
\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\
func Handle ¶
Handle attempts to acquire a system handle for the volume represented by path (or upon which path is mounted).
The given path may be in any of these forms:
C:\path\to\directory\
X:\
Y:\MountX\
\\.\X:
\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\
\\.\PhysicalDrive0
func MountPoint ¶
MountPoint attempts to find the volume mount point for s. If successful, it returns both the volume mount point and the volune name (also known as the volume GUID path).
s may be in any of these forms:
C:\path\to\directory\
X:\
Y:\MountX\
\\.\X:
\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\
\\.\PhysicalDrive0
If successful, the returned volume name will be of this form:
\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\
