40 .Dq Unified Extensible Firmware Interface
42 Device Paths, as defined in the UEFI standard, to and from binary form.
43 Binary and textual forms are defined in Chapter 9 of the UEFI
48 Formats a binary UEFI Device Path into its canonical UTF-8 textual form.
49 A binary Device Path can be no longer than 8192 bytes.
50 The textual form must fit into 4096 bytes.
52 Parses a UEFI Device Path UTF-8 specification and outputs the binary
54 Only one device path is parsed, even if there are multiple present in
56 Leading white space is ignored.
57 The resulting binary Device Path can be no longer than 8192 bytes.
60 Appendix A of the UEFI specification has the format for GUIDs.
62 .Dq Globally Unique Identifiers
63 have the format described in RFC 4122.
