int uuidMutexDestroy

(

)

Destroy mutex for synchronizing the uuid creation process.

Returns

• On success: 0
• On error: EBUSY

Here is the caller graph for this function:

uuid_create()

int uuid_create

(

uuid_upnp *

uid

)

Generate a UUID.

Returns

Always 1.

Parameters

[out]

uid

Pointer to a place for the created uuid.

Here is the caller graph for this function:

upnp_uuid_unpack()

void upnp_uuid_unpack	(	uuid_upnp *	u,
		char *	out
	)

Unpack a UUID.

Parameters

[in]	u	Packed UUID.
[out]	out	Will be xxxx-xx-xx-xx-xxxxxx format.

Definition at line 242 of file uuid.cpp.

Here is the caller graph for this function:

uuid_create_from_name()

void uuid_create_from_name	(	uuid_upnp *	uid,
		uuid_upnp	nsid,
		void *	name,
		int	namelen
	)

Create a UUID using a "name" from a "name space".

Parameters

[out]	uid	Resulting UUID.
[in]	nsid	UUID to serve as context, so identical names from different name spaces generate different UUIDs.
[in]	name	The name from which to generate a UUID.
[in]	namelen	The length of the name.

Definition at line 250 of file uuid.cpp.

Here is the call graph for this function:

uuid_compare()

int uuid_compare	(	uuid_upnp *	u1,
		uuid_upnp *	u2
	)

Compare two UUID's "lexically".

Returns

• -1: u1 is lexically before u2
•  0: u1 is equal to u2
•  1: u1 is lexically after u2

Note

Lexical ordering is not temporal ordering!

Parameters

[in]	u1
[in]	u2
