1.30.4                                            Jun 08, 2025                                   BSON_AS_JSON(3)

bson_as_json() encodes bson as a UTF-8 string using libbson'sLegacyExtendedJSON.

       The  caller is responsible for freeing the resulting UTF-8 encoded string by calling bson_free() with the
       result.

       If non-NULL, length will be set to the length of the result in bytes.

       • bson: A bson_t.

       • length: An optional location for the length of the resulting string.

       If successful, a newly allocated UTF-8 encoded string and length is set.

       Upon failure, NULL is returned.

          char *
          bson_as_json (const bson_t *bson, size_t *length);

          Deprecated      since      version      1.29.0:      Use     bson_as_canonical_extended_json()     and
          bson_as_relaxed_extended_json() instead, which use the same MongoDBExtendedJSONformat as all  other
          MongoDB drivers.

          To continue producing Legacy Extended JSON, use bson_as_legacy_extended_json().
