Specifies the number of UUIDs to generate.ĭisplays version information about Uuidgen. Redirects output to a file specified immediately after the /o switch. Outputs UUID as an initialized C structure. Outputs UUID to an IDL interface template. When you run the Uuidgen utility from the command line, you can use the following command switches. The Uuidgen utility generates the UUID in IDL file format or C-language format. Microsoft provides a utility program called Uuidgen to generate your UUIDs. Uninitialized object interface UUIDs should always be referred to as nil UUIDs rather than NULL UUIDs. It is often used in C and C++ programming in conjunction with pointers. The value NULL is the specific value zero. An empty string, an empty database record, or an uninitialized UUID are all examples of nil values. The term nil indicates anything that is zero, blank, empty, or uninitialized. The following example is a valid UUID string:Įmpty UUIDs are referred to as nil UUIDs rather than NULL UUIDs. The textual representation of a UUID is a string consisting of 8 hexadecimal digits followed by a hyphen, followed by three hyphen-separated groups of 4 hexadecimal digits, followed by a hyphen, followed by 12 hexadecimal digits.

A UUID is a string that contains a set of hexadecimal digits. Therefore, developers typically assign a Universal Unique Identifier (UUID, interchangeable with the term GUID, or Globally Unique Identifier) to each interface. However, that is usually not feasible on large networks. On small networks, the interface's name alone may be sufficient to identify it. This section presents information on Universal Unique Identifiers (UUIDs) and the Uuidgen utility in the following topics:Īll interfaces must be uniquely identified on a network so that clients can find them.
