You're creating a LOCAL string here with space for only TWO letters.

If you enter more than 2 letters here, the results are undefined.

Here you return the pointer to the local string, which is then promptly
'destroyed' - referencing this address after this point results in undefined
behaviour.

The pointer returned from call() is not useable.

What string are you expecting at address 0?
printf("%s\n",name+j);
