[Kde-bindings] Re: one general question

[Sven Aßmann]

For interested:

i found the problem on a zend header:
have a look at the first macro and find the error :)

#define INIT_OVERLOADED_CLASS_ENTRY(class_container, class_name, functions, 
handle_fcall, handle_propget, handle_propset) \
	INIT_OVERLOADED_CLASS_ENTRY_EX(class_container, class_name, 
sizeof(class_name)-1, functions, handle_fcall, handle_propget, handle_propset, 
NULL, NULL)

ok.. i say it: class_name is a const char* and i learned in the first semester 
that sizeof (char *) is 4 on a 32bit machine like all pointers.. and so it 
cannot be used for determine the right memory size.. 

instead its better to use strlen and add 1 byte for the terminating 0:

#define INIT_OVERLOADED_CLASS_ENTRY(class_container, class_name, functions, 
handle_fcall, handle_propget, handle_propset) \
INIT_OVERLOADED_CLASS_ENTRY_EX(class_container, class_name, 
strlen(class_name)+1, functions, handle_fcall, handle_propget, handle_propset, 
NULL, NULL)

dit you agree that?
