NAME
SSL_state_string,
SSL_state_string_long —
get textual description of state of an
SSL object
SYNOPSIS
#include
<openssl/ssl.h>
const char *
SSL_state_string(const
SSL *ssl);
const char *
SSL_state_string_long(const
SSL *ssl);
DESCRIPTION
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.
NOTES
During its use, an SSL object 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(3) call.
RETURN VALUES
Detailed description of possible states to be included later.
