Functions ¶

func ApplyFileBinding ¶

func ApplyFileBinding(root, source string, readOnly bool) error

ApplyFileBinding creates a global mount of the source in root, with an optional read only flag. The bind filter allows us to create mounts of directories and volumes. By default it allows us to mount multiple sources inside a single root, acting as an overlay. Files from the second source will superscede the first source that was mounted. This function disables this behavior and sets the BINDFLT_FLAG_NO_MULTIPLE_TARGETS flag on the mount.

func RemoveFileBinding ¶

func RemoveFileBinding(root string) error

RemoveFileBinding removes a mount from the root path.

Types ¶

type BindMapping ¶

type BindMapping struct {
	MountPoint string
	Flags      uint32
	Targets    []string
}

func GetBindMappings ¶

func GetBindMappings(volumePath string) ([]BindMapping, error)

GetBindMappings returns a list of bind mappings that have their root on a particular volume. The volumePath parameter can be any path that exists on a volume. For example, if a number of mappings are created in C:\ProgramData\test, to get a list of those mappings, the volumePath parameter would have to be set to C:\ or the VOLUME_NAME_GUID notation of C:\ (\\?\Volume{GUID}\), or any child path that exists.
