I have the following C method in a library which I am trying use with PHP. The method returns an error code and returns the value of an integer passed as a pointer:
int getMyAge(int *age)
if able to find age
*age = // value;
In PHP I would like the SWIG-generated wrapper to return FALSE when an error occurs and the age as an integer when successful. PHP models this in other APIs by returning the “mixed” type. Is there a way to do this with custom typemaps in SWIG?
I am able to use simple typemaps in SWIG to get the SWIG-generated wrapper to return an array which contains the error code and age. I know I could write a PHP function around this which provides the behavior I want. I was wondering if there is a way to do this with typemaps or other SWIG capabilities without the need for wrapper functions.
I am using SWIG 3.0.0 to expose this C method to PHP (ver. 5.3.10).
Thanks in advance for any help you can provide.
