NAME

       mongoc_collection_replace_one - mongoc_collection_replace_one()

SYNOPSIS

          bool
          mongoc_collection_replace_one (mongoc_collection_t *collection,
                                         const bson_t *selector,
                                         const bson_t *replacement,
                                         const bson_t *opts,
                                         bson_t *reply,
                                         bson_error_t *error);

       WARNING:
          If  not  NULL,  reply  is  always  initialized, even upon failure. Callers must call bson_destroy() to
          release this potential allocation.

PARAMETERS

       • 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.

       • opts: A bson_t containing additional options or NULL.

       • 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:

       • readConcern: Construct a mongoc_read_concern_t and  use  mongoc_read_concern_append  to  add  the  read
         concern to opts. See the example code for mongoc_client_read_command_with_opts.

       • 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 mongoc_client_write_command_with_opts.

       • sessionId:   Construct   a   mongoc_client_session_t   with   mongoc_client_start_session    and    use
         mongoc_client_session_append   to   add   the   session   to   opts.   See   the   example   code   for
         mongoc_client_session_t.

       • validate: 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.

       • serverId: To target a specific server, include an int32 "serverId" field.  Obtain  the  id  by  calling
         mongoc_client_select_server, then mongoc_server_description_id on its return value.

       • upsert A boolean, when true, creates a new document if no document matches the query.

DESCRIPTION

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

       If  you  pass a non-NULL reply, it is filled out with fields "modifiedCount" and "matchedCount". 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().

SEE ALSO

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

ERRORS

       Errors are propagated via the error parameter.

RETURNS

       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.

       If provided, reply will be initialized and populated with the  fields  matchedCount,  modifiedCount,  and
       optionally upsertedId if applicable.
