28 The bson_context_t structure is context for generation of BSON Object
29 IDs. This context allows overriding behavior of generating ObjectIDs.
30 The flags BSON_CONTEXT_NONE, BSON_CONTEXT_THREAD_SAFE, and BSON_CON‐
31 TEXT_DISABLE_PID_CACHE are the only ones used. The others have no ef‐
32 fect.
