14 =head1 DESCRIPTION
15
16 SSL_rstate_string() returns a 2 letter string indicating the current read state
17 of the SSL object B<ssl>.
18
19 SSL_rstate_string_long() returns a string indicating the current read state of
20 the SSL object B<ssl>.

22 =head1 NOTES
23
24 When performing a read operation, the SSL/TLS engine must parse the record,
25 consisting of header and body. When working in a blocking environment,
26 SSL_rstate_string[_long]() should always return "RD"/"read done".
27
28 This function should only seldom be needed in applications.
