Hi,
while (((rc = SSL_accept(ssl)) <= 0) &&
((SSL_get_error(ssl, rc) == SSL_ERROR_WANT_READ) ||
(SSL_get_error(ssl, rc) == SSL_ERROR_WANT_WRITE)))
{
/* as on wait application can do something else */
do_other_stuff();
}
hope you have called
SSLBio = BIO_new_socket(ulFd, BIO_NOCLOSE);
* Sets the BIO associated with Socket FD to Non Blocking Mode */
BIO_socket_ioctl(ulFd,FIONBIO,&Switch)
SSL_set_bio(SSLObj,SSLBio,SSLBio)
int ssl_accept()
{
/* Do the handshake */
iRetVal = SSL_accept(SSLObj);
if(iRetVal == 1)
{
return 1;
}
else
{
iRetVal = SSL_get_error(SSLObj, iRetVal);
switch(iRetVal)
{
case SSL_WANT_READ:
case SSL_WANT_ACCEPT:
/* This means that the SSL_accept is blocked and should be
retried when the fd is available for reading. So, add to the
poll table to look for READ event */
/* application should poll for READ */
return(SSL_WANT_READ);
case SSL_WANT_WRITE:
case SSL_WANT_CONNECT:
/* This means that the SSL_accept is blocked and should be
retried when the fd is available for writing. So, add to the
poll table to look for WRITE event */
/* application should poll for WRITE */
return(SSL_WANT_WRITE);
default:
/* Abort the accept as its a permanent error */
return 0;
}
}
}

Hi there, I am pulling my hair out trying to get SSL_accept to work with a
non blocking socket. When I make a call to SSL_accept and then perform an
SSL_get_error. I get the error SSL_ERROR_WANT_READ. At this point what
should I do. Currently I am doing the following:
while (((rc = SSL_accept(ssl)) <= 0) &&
((SSL_get_error(ssl, rc) == SSL_ERROR_WANT_READ) ||
(SSL_get_error(ssl, rc) == SSL_ERROR_WANT_WRITE)))
{}
but I never get out of this loop.
I am also using select to obtain read events for this socket. In the case
mentioned above do I need to check select for a read event prior to
calling retrying SSL_accept.
HELP MUCH APPRECIATED!
