SYNOPSIS

          bool
          mongoc_collection_command_with_opts (
             mongoc_collection_t *collection,
             const bson_t *command,
             const mongoc_read_prefs_t *read_prefs,
             const bson_t *opts,
             bson_t *reply,
             bson_error_t *error);

       Execute  a  command  on  the  server,  interpreting  opts  according to the MongoDB server
       version.  To  send  a  raw  command  to  the  server  without  any  of  this  logic,   use
       mongoc_client_command_simple().

       Read  preferences,  read  and  write  concern,  and collation can be overridden by various
       sources. The highest-priority sources for these options are listed first:

                     ┌─────────────────┬──────────────┬───────────────┬───────────┐
                     │Read Preferences │ Read Concern │ Write Concern │ Collation │
                     ├─────────────────┼──────────────┼───────────────┼───────────┤
                     │read_prefs       │ opts         │ opts          │ opts      │
                     ├─────────────────┼──────────────┼───────────────┼───────────┤
                     │Transaction      │ Transaction  │ Transaction   │           │
                     └─────────────────┴──────────────┴───────────────┴───────────┘

       In a transaction, read concern and write concern are  prohibited  in  opts  and  the  read
       preference  must  be  primary  or  NULL.   See  the  example  for transactions and for the
       "distinct" command with opts.

       reply is always initialized, and must be freed with bson_destroy().

PARAMETERS

       • collection: A mongoc_collection_t.

       • command: A bson_t containing the command specification.

       • read_prefs: An optional mongoc_read_prefs_t.

       • opts: A bson_t containing additional options.

       • reply: A maybe-NULL pointer to overwritable storage for a bson_t to contain the results.

       • 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(). Read concern  requires  MongoDB  3.2  or  later,
         otherwise an error is returned.

       • 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:       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.

       • 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.

       • 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.

       Consult the MongoDB Manual entry on Database Commands for each command's arguments.

       This function is not considered a retryable read operation.

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.

       The reply is not parsed for a write concern timeout or write concern error.

EXAMPLE

       See the example code for mongoc_client_read_command_with_opts().
