Your code is broken in several ways. For one thing, when is the loop
supposed to return, assuming there is no error?

Shouldn't there be a 'break' here?

> loop=FALSE; /* get out of loop */
> printf("No more data \n");

The code you posted, even with the missing 'break' appears to continue
reading the data on an SSL connection, overwriting each 32 bytes with the
next 32 bytes, until the other side closes the connection or an error
occurs. It's hard to imagine how that's useful.
