       The tlsrpt_errno_from_error_code function returns the errno part of an errorcode. In case of internal
       library errors from the TLSRPT_ERR_TLSRPT block the returned value will be a high number to avoid clashes
       with existing errno values. I.e. TLSRPT_ERR_TLSRPT_NESTEDPOLICY is 10731 instead of 10031 to avoid the
       errno part being decoded as EMLINK.

       The tlsrpt_errno_from_error_code function returns 0 on success and a combined error code on failure. The
       combined error code can be analyzed with the tlsrpt_strerror function.
