Subject: zval "passthrough"?
From: david.olsson@vimio.com (David Olsson)

Hello

I'm writing a PHP extension in C++ which need to provide a function 
which will take as a parameter a zval *. This zval * should, when the 
function has completed its task, simply be returned unmodified. How do I 
accomplish this? I've tried something like this:

PHP_FUNCTION(my_func) {
	zval *v;
	if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", &v) == FAILURE) {
		WRONG_PARAM_COUNT;
	}

	.
	.
	.

	return_value = v;
}

The above doesn't seem to be working at all though. Any ideas? I guess 
it is a really simple task once you known how do actually do it... :-)

Thankful for all help!
