NAME
mongoc_client_command_simple - mongoc_client_command_simple()
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_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
Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error. This function does not check the server response for a write concern error or write concern timeout.
