bson_iter_code − bson_iter_code()
#define BSON_ITER_HOLDS_CODE(iter) (bson_iter_type ((iter)) == BSON_TYPE_CODE) const char * bson_iter_code (const bson_iter_t *iter, uint32_t *length);
• |
iter: A bson_iter_t. | ||
• |
length: A location for the length of the UTF−8 encoded string or NULL. |
This function returns the contents of a BSON_TYPE_CODE field. The length of the string is stored in length if non−NULL.
