How do you use Inline::C to call a C function returning a struct but
receive it in Perl as a hash? For example, if we look at getpwuid it
returns a struct passwd * (forgive me my C is very rusty). I could not
get this to bind with Inline::C. I had to do:
#include <pwd.h>
typedef struct passwd Passwd;
Passwd *getpasswd (uid_t uid) {
return getpwuid (uid);
}
As well as a typemap file of:
uid_t T_IV
Passwd * T_PTRREF
Now I can bind and call my "getpasswd" stub (which in turn calls
getpwuid) but all I get back is a reference. I would like to be able to
pass back a hash with the keys being the member names (e.g. pw_name,
pw_passwd, etc). I realize this can quickly become complex as structs
can have other complex data types, etc. Is this doable? Is it sane?

Why does "fat chance" and "slim chance" mean the same thing?
