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.
