SSL_state_string, SSL_state_string_long - get textual description of state of an
SSL object
#include <openssl/ssl.h>
const char *SSL_state_string(const SSL *ssl);
const char *SSL_state_string_long(const SSL *ssl);
SSL_state_string() returns an abbreviated string indicating the current
state of the SSL object
ssl. The returned NUL-terminated string
contains 6 or fewer characters.
SSL_state_string_long() returns a descriptive 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 nonblocking 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 nonblocking sockets, the details state information can be
used within the info_callback function set with the
SSL_set_info_callback() call.
Detailed description of possible states to be included later.
