1=pod 2 3=head1 NAME 4 5SSL_state_string, SSL_state_string_long - get textual description of state of an SSL object 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 const char *SSL_state_string(const SSL *ssl); 12 const char *SSL_state_string_long(const SSL *ssl); 13 14=head1 DESCRIPTION 15 16SSL_state_string() returns an abbreviated string indicating the current state 17of the SSL object B<ssl>. The returned NUL-terminated string contains 6 or fewer characters. 18 19SSL_state_string_long() returns a descriptive string indicating the current state of 20the SSL object B<ssl>. 21 22=head1 NOTES 23 24During its use, an SSL objects passes several states. The state is internally 25maintained. Querying the state information is not very informative before 26or when a connection has been established. It however can be of significant 27interest during the handshake. 28 29When using nonblocking sockets, the function call performing the handshake 30may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition, 31so that SSL_state_string[_long]() may be called. 32 33For both blocking or nonblocking sockets, the details state information 34can be used within the info_callback function set with the 35SSL_set_info_callback() call. 36 37=head1 RETURN VALUES 38 39Detailed description of possible states to be included later. 40 41=head1 SEE ALSO 42 43L<ssl(7)>, L<SSL_CTX_set_info_callback(3)> 44 45=head1 COPYRIGHT 46 47Copyright 2001-2021 The OpenSSL Project Authors.
