UUID parsing and serialization utilities. The library treat the UUID as an opaque sequence of 16 unsigned bytes, i.e. ignoring the internal layout of the UUID, which depends on the type of the UUID.
Definition in file uuid.c.
Parses a string representation of a UUID formatted according to IETF RFC 4122 into an AVUUID.
The parsing is case-insensitive. The string must be 37 characters long, including the terminating NUL character.
Example string representation: "2fceebd0-7017-433d-bafb-d073a7116696"

Parses a string representation of a UUID formatted according to IETF RFC 4122 into an AVUUID.
The parsing is case-insensitive.
[in] | in_start | Pointer to the first character of the string representation |
[in] | in_end | Pointer to the character after the last character of the string representation. That memory location is never accessed. It is an error if in_end - in_start != 36 . |

Serializes a AVUUID into a string representation according to IETF RFC 4122.
The string is lowercase and always 37 characters long, including the terminating NUL character.
[in] | uu | AVUUID |
[out] | out | Pointer to an array of no less than 37 characters. |
Parses a URN representation of a UUID, as specified at IETF RFC 4122, into an AVUUID.
The parsing is case-insensitive. The string must be 46 characters long, including the terminating NUL character.
Example string representation: "urn:uuid:2fceebd0-7017-433d-bafb-d073a7116696"
