bool
mongoc_database_command_simple (mongoc_database_t *database,
const bson_t *command,
const mongoc_read_prefs_t *read_prefs,
bson_t *reply,
bson_error_t *error);
Parameters¶
database
: A mongoc_database_t.command

.reply

This is a simplified interface to mongoc_database_command() that returns the first result document. The database’s read preference, read concern, and write concern are not applied to the command. The parameter reply
is initialized even upon failure to simplify memory management.
Errors¶
Errors are propagated through 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.
