#define BSON_ITER_HOLDS_DOCUMENT(iter) \
(bson_iter_type ((iter)) == BSON_TYPE_DOCUMENT)
void
bson_iter_document (const bson_iter_t *iter,
uint32_t *document_len,
const uint8_t **document);
Parameters¶
- iter: A bson_iter_t.
- document_len: A location for the length of the document in bytes.
- document: A location for the document buffer.
Description¶
