          mongoc_collection_replace_one (mongoc_collection_t *collection,
                                         const bson_t *selector,
                                         const bson_t *replacement,

       · collection: A mongoc_collection_t.

       · selector: A bson_t containing the query to match the document for updating.

       · replacement: A bson_t containing the replacement document.

       · reply: Optional. An uninitialized bson_t populated with the update result, or NULL.

       · error: An optional location for a bson_error_t or NULL.

       opts may be NULL or a BSON document with additional command options:

       · writeConcern:  Construct a mongoc_write_concern_t and use mongoc_write_concern_append to
         add    the    write    concern    to    opts.    See    the     example     code     for

       · sessionId:  First, construct a mongoc_client_session_t with mongoc_client_start_session.
         You can begin a  transaction  with  mongoc_client_session_start_transaction,  optionally
         with  a  mongoc_transaction_opt_t  that overrides the options inherited from collection,
         and use mongoc_client_session_append to add the session to opts. See  the  example  code
         for mongoc_client_session_t.

       · validate:  Construct  a bitwise-or of all desired bson_validate_flags_t. Set to false to
         skip client-side validation of the provided BSON documents.

       · bypassDocumentValidation: Set to true to  skip  server-side  schema  validation  of  the
         provided BSON documents.

       · collation:  Configure  textual comparisons. See Setting Collation Order, and the MongoDB
         Manual entry on Collation. Collation requires MongoDB 3.2 or later, otherwise  an  error
         is returned.

       · upsert: When true, creates a new document if no document matches the query.


       This function shall replace documents in collection that match selector with replacement.

       If  provided,  reply  will  be  initialized  and  populated  with the fields matchedCount,
       modifiedCount, upsertedCount, and optionally upsertedId  if  applicable.  If  there  is  a
       server  error  then  reply  contains  either a writeErrors array with one subdocument or a
       writeConcernErrors array. The reply must be freed with bson_destroy().


       MongoDB update command documentation for more information on the update options.

       Errors are propagated via the error parameter.


       Returns true if successful. Returns false and sets error if there are invalid arguments or
       a server or network error.

       A write concern timeout or write concern error is considered a failure.
