A value of 0 enables waiting indefinitely, while a value < 0 immediately leads to a timeout condition.</p> <p>X509_http_nbio() and X509_CRL_http_nbio() are macros for backward compatibility that have the same effect as the functions above but with infinite timeout and without the possibility to specify custom BIOs.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>On success the function yield the loaded value, else NULL.
