SSL_state_string, SSL_state_string_long — get textual description of state of an SSL object
char *SSL_state_string(SSL *ssl);
const char *SSL_state_string_long(SSL
SSL_state_string() returns a 6 letter string indicating the
current state of the SSL object ssl.
SSL_state_string_long() returns a string indicating the current
state of the SSL object ssl.
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.
