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(....)
}
}
Thanks a lot, it seems to work.
Also take a look in Zend/zend.h at the definitions for
INTERNAL_FUNCTION_PARAMETERS and
INTERNAL_FUNCTION_PARAM_PASSTHRU
I will. Thanks again.
which can be used in you own function declarations to handle
the php function paramters.
Hope that helps,

Subject: [PHP-DEV] help request: passing return value
Hi internals.
[background]
I'm newbie here and with php extensions.
Working on php extension.
It should give access to librep.
I have very little experience with C.
[problem]
zval f1(some_args) {
zval r;
...
return r;
}
/* f1 can return many different types */
ZEND_FUNCTION(f2) {
/* working on some_args here */
...
...
/* here i need to return what
f1(some_args) returns */
}
What's the best way to pass the result ?
Any macro that would ?
[tried]
To look at another modules.
Make f1 be (zval *) and
"*return_value=*rep_data_converter(result);"
in f2.
Since zval is not very simple structure - it doesn't work.
