-/*
- * Converts a Python object into a data for a berval structure.
- *
- * New memory is allocated, and the content of the object is copied into it.
- * Then the (pre-existing) berval structure's field are filled in with pointer
- * and length data.
- *
- * The source object must implement the buffer interface, or be None.
- * If the source object is None, bv->bv_val will be set to NULL and bv_len to 0.
- * Otherwise, bv->bv_val will be non-NULL (even for zero-length data).
- * This allows the caller to distinguish a None argument as something special.
- *
- * Returns 0 on failure, leaving *bv unchanged, and setting an error.
- * Returns 1 on success: the berval must be freed with LDAPberval_release().
