Hi Stephen,
I added debug code as:
int retryCounter = 0;
while(retryCounter < CONNECT_MAX_TRY)
{
int retVal = BIO_do_connect(conn);
if(retVal <= 0)
{
if(BIO_should_retry(conn))
{
retryCounter++;
sleep(CONNECT_SLEEP_INTERVAL);
FILE * pFile;
pFile = fopen ("result_retry.txt","a");
if (pFile!=NULL)
{
ERR_print_errors_fp(pFile);
}
continue;
}
else
{
FILE * pFile1;
pFile1 = fopen ("result.txt","a");
if (pFile1!=NULL)
{
ERR_print_errors_fp(pFile1);
}
cout << " The Bio_do_connect failed" << endl;
}
}
}
After execution of program, I saw that only "result.txt" file is getting
created and not the "result_retry.txt" file which clarifies that the retry
logic is working fine. Problem comes when retry counter reaches its max
value and Bio_do_connect() gets failed. Though my understanding might be
wrong here.
But the main problem which I encountered today is that nothing is being
written in the file "result.txt" and I am also hoping that I am using the
ERR_print_errors_fp() function in correct way. The file is blank. Then just
to make sure that pFile1 handle returned as Not NULL and we are entering
inside the if check, I added statement
If(pfile1! = NULL)
{
fputs ("fopen example",pFile);
//ERR_print_errors_fp(pFile1);
}
And this time, I could see that "fopen example" is being written to
result.txt file successfully.
So, could you please suggest what mistake I am doing here that SSL errors
are not being getting written in file and also any other suggestions to try
out.
Thanks
Akanksha Shukla.

Try adding some more debugging code to see if it actually does retry and
also
if it fails call the OpenSSL ERR library to print out any useful message.
For
example ERR_print_errors_fp(stderr);
Steve.
