I am facing some weird problem in SSL_write(). Most of the times it returned with "SSL_ERROR_SSL".
Can anyone explain what is this error and how can we fix this.
I am using 0.9.8g openssl version.

Any assistance (including temporary workarounds) appreciated.

Thanks....

Hi

I use to write data to openssl the follow function

int hb_inetSSLWrite(int com,SSL* pSSL, int timeout, char * msg, int
length, int* iRet)
{

   int ret;
   int sslerr;
   int r;
   fd_set fd_r, fd_w;
   struct timeval tv;

   do
   {
      ret = SSL_write(pSSL, msg, length);
      sslerr = SSL_get_error(pSSL, ret);

      if ( ret > 0)
      {
        r = 1;
        *iRet = 0;
        break;
      }
      *iRet = sslerr;
      FD_ZERO( &fd_r );
      FD_ZERO( &fd_w );
      if( timeout > 0 )
      {
         tv.tv_sec = timeout  / 1000;
         tv.tv_usec = ( timeout % 1000 ) * 1000;
      }

      switch (sslerr)
      {
         case SSL_ERROR_WANT_READ:
            FD_SET(com,&fd_r);
            break;
         case SSL_ERROR_WANT_WRITE:
            FD_SET(com,&fd_w);
            break;
         default:
            return -1;
      }
      if( timeout > 0 )
         r = select(com+1,&fd_r,&fd_w,NULL,&tv);
      else
         r = select(com+1,&fd_r,&fd_w,NULL,NULL);

   } while ( ret == -1 && r != 0 );

   if ( r == 0)
      return -1;

   return ret;
}

Regards
Luiz

After (any) SSL_* returns SSL_ERROR_SSL, to get more detailed
information about the error(s) either:
- call ERR_get_error (note different name) to get an unsigned long,
then ERR_error_string (and/or other ERR_*) routines to decode it,
and display, and repeat until ERR_get_error returns zero; or
- call ERR_print_errors_fp (stderr or other FILE*) which
does the above for you in a default format.
