표 42-1. api macros for accessing zval containers
macro

note: all conversion functions expect a **zval as parameter.
strings containing a number are converted to their corresponding numeric representation, otherwise resulting in 0.0.

o - object (of any class), stored in zval*
_bar_ - indicates that the remaining parameters are optional.

o - object (of class specified by class entry), stored in zval*
the storage variables corresponding to these parameters should be initialized to default values by the extension, since they will not be touched by the parsing function if the parameters are not passed.

what is really going on when you register a new resource is it gets inserted in an internal list in zend and the result is just stored in the given zval * container:
rsrc_id = zend_list_insert( rsrc_pointer, rsrc_type); if (rsrc_result) {rsrc_result - value.lval = rsrc_id; rsrc_result - type = is_resource;} return rsrc_id;

a set of macros was introduced into zend's api that simplify access to zval containers (see 표 42-1).
