+=head1 NAME
+
+SSL_state_string, SSL_state_string_long - get textual description of state of an SSL object
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ char *SSL_state_string(SSL *ssl);
+ char *SSL_state_string_long(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.
