bson_array_as_json (const bson_t *bson, size_t *length);
|

bson: A bson_t. |
|||
|
• |
length: An optional location for the length of the resulting string. |
The bson_array_as_json() function shall encode bson as a UTF−8 string using libbson's legacy JSON format, except the outermost element is encoded as a JSON array, rather than a JSON document. This function is superseded by bson_array_as_canonical_extended_json() and bson_array_as_relaxed_extended_json(), which use the same MongoDB Extended JSON format as all other MongoDB drivers. 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.
If successful, a newly allocated UTF−8 encoded string and length is set.
Upon failure, NULL is returned.
