# mongoc\_uri\_set\_compressors(3)

## SYNOPSIS

```
bool
mongoc_uri_set_compressors (mongoc_uri_t *uri, const char *compressors);
```

## PARAMETERS

- •

  **uri**: A *mongoc\_uri\_t*.

- •

  **compressors**: A string consisting of one or more comma (,) separated compressors (e.g. "snappy,zlib") or **NULL**. Passing **NULL** clears any existing compressors set on **uri**.

## DESCRIPTION

Sets the URI's compressors, after the URI has been parsed from a string. Will overwrite any previously set value.

## EXAMPLE

```
mongoc_client_t *client;
mongoc_uri_t *uri;
uri = mongoc_uri_new ("mongodb://localhost/");
mongoc_uri_set_compressors (uri, "snappy,zlib,zstd");
mongoc_client_new_from_uri (uri);
/* Snappy & zlib & zstd compressors are enabled */
```

## RETURNS

Returns false if the option cannot be set, for example if **compressors** is not valid UTF-8. Logs a warning to stderr with the *MONGOC\_WARNING* macro if compressor is not available.
