Synopsis

bool
mongoc_client_command_simple (mongoc_client_t *client,
                              const char *db_name,
                              const bson_t *command,
                              const mongoc_read_prefs_t *read_prefs,
                              bson_t *reply,
                              bson_error_t *error);

This is a simplified interface to mongoc_client_command(). It returns the first document from the result cursor into reply. The client's read preference, read concern, and write concern are not applied to the command.

WARNING:

reply is always set, and should be released with bson_destroy().

Parameters

·

client: A mongoc_client_t.

·

db_name: The name of the database to run the command on.

·

command: A bson:bson_t containing the command specification.

·

read_prefs: An optional mongoc_read_prefs_t. Otherwise, the command uses mode MONGOC_READ_PRIMARY.

·

reply: A location for the resulting document.

·

error: An optional location for a bson_error_t or NULL.

Errors

Errors are propagated via the error parameter.

Returns

true if successful; otherwise false and error is set.
