BSON_AS_JSON(3) libbson BSON_AS_JSON(3)

WARNING:

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

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



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


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

bson_as_json() encodes bson as a UTF-8 string using libbson's Legacy Extended JSON.

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.
