No passphrase question with PEM_X509_INFO_read_bio

[Resul Cetin]

Hi,
I am currently trying to load an encrypted certificate with 

PEM_X509_INFO_read_bio(in, sk, asdasd, NULL);

This should read an file with encrypted private key (passphase: secret) and 
not encrypted cert. It should start to read both and then ask for the 
passphrase. I currently test it with following dummy function:

int asdasd(char *buf, int size, int rwflag, void *password)
{
        printf("asdasd\n");
        exit(1);
        return 1;
}

The problem is that it will not be called. I did a recheck with
 PEM_read_bio_PrivateKey(in, NULL, asdasd, NULL);
and it did ask for the passphrase.
 PEM_read_bio_X509(in, NULL, asdasd, NULL);
also didn't asked for an passphrase.

Is there any secret thing I have to do to get this thing working?

My testcode is attached. It should print "asdasd" and return 1. If it doesn't 
print anything and returns (-)1 then it cannot find the server.cert in the 
current directory. If it prints nothing and it returns 0 then it didn't asked 
for the passphrase.

I need to parse a big file with certificates... so I wanted to use 
PEM_X509_INFO_read_bio as this seems to read all at once.
