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