Hello,

I would like to use zend_parse_parameters() to retrieve a zval** but it
currently does not do this. get_parameters() which does return zval**'s has been
deprecated. I don't want to use the '/' option with zend_parse_parameters()
because zval separation may not be necessary, and I would like to avoid it
whenever possible.

    The old APIs are not really deprecated.  The new APIs are
    simply recommended over the old ones.  So, if you are running
    into a case where zend_get_parameters works better for you,
    go ahead and use it.

Ok, thanks.

Is there a reason why this functionality is not supported in the new API?

Second time around.

This patch would add a 'Z' flag to zend_parse_parameters*().

Example:

    #typdef zvar zval**

    zvar a_zvar;

    zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "Z", &zvar);

One more time. I hope it's not too obvious that I'm new at this :)

This patch would add a 'Z' flag to zend_parse_parameters*().

Example:
    #typdef zvar zval**
    zvar a_zvar;
    zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "Z", &zvar);

That should be &a_var, right?

It looks like you have an extra tab in front of that new 'case'.

First off, what do you need access to zval** for, exactly?
