1=pod 2 3=head1 NAME 4 5SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 const char *SSL_rstate_string(SSL *ssl); 12 const char *SSL_rstate_string_long(SSL *ssl); 13 14=head1 DESCRIPTION 15 16SSL_rstate_string() returns a 2 letter string indicating the current read state 17of the SSL object B<ssl>. 18 19SSL_rstate_string_long() returns a string indicating the current read state of 20the SSL object B<ssl>. 21 22=head1 NOTES 23 24When performing a read operation, the SSL/TLS engine must parse the record, 25consisting of header and body. When working in a blocking environment, 26SSL_rstate_string[_long]() should always return "RD"/"read done". 27 28This function should only seldom be needed in applications. 29 30=head1 RETURN VALUES 31 32SSL_rstate_string() and SSL_rstate_string_long() can return the following 33values: 34 35=over 4 36 37=item "RH"/"read header" 38 39The header of the record is being evaluated. 40 41=item "RB"/"read body" 42 43The body of the record is being evaluated. 44 45=item "RD"/"read done" 46 47The record has been completely processed. 48 49=item "unknown"/"unknown" 50 51The read state is unknown. This should never happen. 52 53=back 54 55=head1 SEE ALSO 56 57L<ssl(7)> 58 59=head1 COPYRIGHT 60 61Copyright 2001-2016 The OpenSSL Project Authors.
