bson_compare()
Synopsis
int bson_compare (const bson_t *bson, const bson_t *other);
Description
The bson_compare() function shall compare two bson documents for equality.
This can be useful in conjunction with _qsort()_.
If equal, 0 is returned.
This function uses _memcmp()_ internally, so the semantics are the same.
Returns
less than zero, zero, or greater than zero in qsort() style.
