Declared in `<bdlb_guidutil.h>`

Generate a sequence of GUIDs meeting the RFC 4122 version 4 specification, and load the resulting GUIDs into the array referred to by the specified `result`. Optionally specify `numGuids`, indicating the number of GUIDs to load into the `result` array. If `numGuids` is not supplied, a default of 1 is used. An RFC 4122 version 4 GUID consists of 122 randomly generated bits, two "variant" bits set to `10`, and four "version" bits set to `0100`. The behavior is undefined unless `result` refers to a contiguous sequence of at least `numGuids` `Guid` objects.

Generate a sequence of GUIDs meeting the RFC 4122 version 4 specification, and load the bytes of the resulting GUIDs into the array referred to by the specified `result`. Optionally specify `numGuids`, indicating the number of GUIDs to load into the `result` array. If `numGuids` is not supplied, a default of 1 is used. An RFC 4122 version 4 GUID consists of 122 randomly generated bits, two "variant" bits set to `10`, and four "version" bits set to `0100`. The behavior is undefined unless `result` refers to a contiguous sequence of at least `16 * numGuids` bytes.
