I have a PHP_FUNCTION() defined in my PHP extension.  How am I suppose to
pass variables by reference to my function without enabling call-time pass
by reference in the PHP.INI file?

Thanks

Hello Chris,

you need to define that signature of your functions by supplying
ZEND_ARG_INFO's to them. look at ZEND_API.h file for those macros.

look at
http://cvs.php.net/co.php/php-src/ext/mcve/mcve.c?r=1.28.2.2

the m_completeauthorizations  function.

I think the definition in the C syntax of PHP_FUNCTION will do that for you.

You'll probably need to use some ZEND_xxx macro.

Check out simple functions (error_log springs to mind) that use pass by
reference.
