SSL_rstate_string() returns a 2 letter string indicating the current read state of the SSL object ssl.

       SSL_rstate_string_long() returns a string indicating the current read state of the SSL object ssl.

       SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read
       operation

       When performing a read operation, the SSL/TLS engine must parse the record, consisting of header and
       body. When working in a blocking environment, SSL_rstate_string[_long]() should always return "RD"/"read
       done".

       This function should only seldom be needed in applications.

SSL_rstate_string() and SSL_rstate_string_long() can return the following values:

       "RH"/"read header"
           The header of the record is being evaluated.

       "RB"/"read body"
           The body of the record is being evaluated.

       "unknown"/"unknown"
           The read state is unknown. This should never happen.

       When used with QUIC SSL objects, these functions always return "RH"/"read header" in normal conditions.
