ssl_state_string(3)
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 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.
RETURN VALUES
Detailed description of possible states to be included later.
