3 =head1 NAME
5 SSL_state_string, SSL_state_string_long - get textual description of state of an SSL object
7 =head1 SYNOPSIS
9  #include <openssl/ssl.h>
11  const char *SSL_state_string(const SSL *ssl);
12  const char *SSL_state_string_long(const SSL *ssl);
14 =head1 DESCRIPTION
16 SSL_state_string() returns a 6 letter string indicating the current state
17 of the SSL object B<ssl>.
19 SSL_state_string_long() returns a string indicating the current state of
20 the SSL object B<ssl>.
22 =head1 NOTES
24 During its use, an SSL objects passes several states. The state is internally
25 maintained. Querying the state information is not very informative before
26 or when a connection has been established. It however can be of significant
27 interest during the handshake.
29 When using non-blocking sockets, the function call performing the handshake
30 may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition,
31 so that SSL_state_string[_long]() may be called.
33 For both blocking or non-blocking sockets, the details state information
34 can be used within the info_callback function set with the
35 SSL_set_info_callback() call.
37 =head1 RETURN VALUES
39 Detailed description of possible states to be included later.
