# mongoc\_database\_get\_collection\_names(3)

**WARNING:**

Deprecated since version 1.9.0: Use *mongoc\_database\_get\_collection\_names\_with\_opts()* instead.

## SYNOPSIS

```
char **
mongoc_database_get_collection_names (mongoc_database_t *database,
                                      bson_error_t *error);
```

## DESCRIPTION

Fetches a **NULL** terminated array of **NULL-byte** terminated **char\*** strings containing the names of all of the collections in **database**.

This function is considered a retryable read operation. Upon a transient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If **retryreads** is false in the URI (see *mongoc\_uri\_t*) the retry behavior does not apply.

## PARAMETERS

- •

  **database**: A *mongoc\_database\_t*.

- •

  **error**: An optional location for a *bson\_error\_t* or **NULL**.

## ERRORS

Errors are propagated via the **error** parameter.

## RETURNS

A **NULL** terminated array of **NULL** terminated **char\*** strings that should be freed with *bson\_strfreev()*. Upon failure, **NULL** is returned and **error** is set.
