PHP_FUNCTION (or ZEND_FUNCTION - they are the same)
includes the function paramters; one of those is:
zval *return_value;
which already contains an allocated zval (set to NULL).
If you want to change this in one of your own functions, you could
do something like this:
int f1(zval *return_value, ...)
{
... change the return_value here ...
return SUCCESS;
}
PHP_FUNCTION(my_func)
{
if (f1(return_value) == SUCCESS) {
/* it worked */
return;
} else {
/* it didn't work */
php_error(....)
}
}
Also take a look in Zend/zend.h at the definitions for
INTERNAL_FUNCTION_PARAMETERS and
INTERNAL_FUNCTION_PARAM_PASSTHRU
which can be used in you own function declarations to handle
the php function paramters.
Hope that helps,
