bson_oid_init_sequence - Man Page

void
bson_oid_init_sequence (bson_oid_t *oid, bson_context_t *context)
  BSON_GNUC_DEPRECATED_FOR (bson_oid_init);

• oid: A bson_oid_t.
• context: An optional bson_context_t.

Generates a new ObjectID with the next 64-bit sequence number in context. The first 4 bytes contain the current time and the following 8 contain the sequence number in big-endian format.

The bson_oid_t generated by this function is not guaranteed to be globally unique. Only unique within this context. It is however, guaranteed to be sequential.
