 Type specifiers
 ---------------
- l     - long
- d     - double
- s     - string (with possible null bytes) and its length
- b     - boolean, stored in zend_bool
- r     - resource (stored in zval)
- a     - array
+ The following list shows the type specifier, its meaning and the parameter 
+ types that need to be passed by address. All passed paramaters are set
+ if the PHP parameter is non optional and untouched if optional and the 
+ parameter is not present. The only exception is O where the zend_class_entry*
+ has to be provided on input and is used to verify the PHP parameter is an 
+ instance of that class.
+
+ l     - long (long)
+ d     - double (double)
+ s     - string (with possible null bytes) and its length (char*, int)
+ u     - unicode (UChar*, int)
+ t     - text (void * (char*/Uchar*), int (length), zend_uchar (IS_STRING/..))
+         actual type is controled by ini unicode setting
+ T     - text (void * (char*/Uchar*), int (length), zend_uchar (IS_STRING/..))
+         actual type controlled by first s or u
+ b     - boolean (zend_bool)
+ r     - resource (zval*)
+ a     - array (zval*)
  h     - array (returned as HashTable*)
- o     - object (of any type)
- O     - object (of specific type, specified by class entry)
- z     - the actual zval
+ o     - object of any type (zval*)
+ O     - object of specific type given by class entry (zval*, zend_class_entry)
+ C     - class (zend_class_entry*)
+ z     - the actual zval (zval*)
+ Z     - the actual zval (zval**)
