Hello,
I'm writing a small program using gnutls and its gnutls_record_{recv,send}()
interface. They return a size_t which holds either the number of bytes
transferred or a negative error code.
But on Mac OS X size_t is an unsigned long which gives me grief when
trying to recognise an error code as such.
For a simple read() call this is straightforward to fix: Instead of
if (bytes < 0)
I now use
if (bytes == -1)
Obviously this doesn't work for gnutls error codes which may range from
-1 to -65500. Something like
if ((signed long)bytes < 0)
seems just as wrong to me. Am I missing the obvious here?

Micha
