hi zeev, andy,

Andi's gone till Thursday...

things like: php3i_long_pval & friend don't exist in php4 currently - will you put them into the "official" zend api?

What do they do?

one question, what is the "official" descructor function that modules should use (zend_dtor)? and what do we need to do for the ELS stuff when destructing?

I don't think you need to supply a destructor pointer anywhere - if you're using API functions. If you need to directly destroy a zval, use zval_dtor(). Don't supply zval_dtor() as a destructor function for symbol table hashes though (again, I don't think any non-Zend code should be directly supplying a hash destructor function, but should be using array_init() or object_init() instead).

and again, what is the "official" way to create a new pval - as i mentioned before i think that: pval *value = emalloc(sizeof(pval)); value->type = IS_STRING; value->value.str.len = size; value->value.str.val = estrndup(column->data,size); will leave is_ref and refcount in a undefined state, which is not what we want - what would be the disadvantage for having an api-call for that?

In fact, as I said, you rarely care about refcount - Zend takes care of it for you as long as you use API functions. For example, you never have to set up the reference count information for return_value in internal function implementations. You also don't have to set up the reference count information for any array elements you set using add_assoc_long() and friends.
