The setting for B is overridden from the setting for -a specific SSL object, if specified. -When B is NULL, not callback function is used. - -SSL_set_info_callback() sets the B function, that can be used to -obtain state information for B during connection setup and use. -When B is NULL, the callback setting currently valid for -B is used. - -SSL_CTX_get_info_callback() returns a pointer to the currently set information -callback function for B. - -SSL_get_info_callback() returns a pointer to the currently set information -callback function for B. - -=head1 NOTES - -When setting up a connection and during use, it is possible to obtain state -information from the SSL/TLS engine. When set, an information callback function -is called whenever the state changes, an alert appears, or an error occurs. - -The callback function is called as B. -The B argument specifies information about where (in which context) -the callback function was called. If B is 0, an error condition occurred. -If an alert is handled, SSL_CB_ALERT is set and B specifies the alert -information. - -B is a bitmask made up of the following bits: - -=over 4 - -=item SSL_CB_LOOP - -Callback has been called to indicate state change inside a loop. - -=item SSL_CB_EXIT - -Callback has been called to indicate error exit of a handshake function. -(May be soft error with retry option for non-blocking setups.) - -=item SSL_CB_READ - -Callback has been called during read operation. - -=item SSL_CB_WRITE - -Callback has been called during write operation. - -=item SSL_CB_ALERT - -Callback has been called due to an alert being sent or received. - -=item SSL_CB_READ_ALERT (SSL_CB_ALERT|SSL_CB_READ) - -=item SSL_CB_WRITE_ALERT (SSL_CB_ALERT|SSL_CB_WRITE) - -=item SSL_CB_ACCEPT_LOOP (SSL_ST_ACCEPT|SSL_CB_LOOP) - -=item SSL_CB_ACCEPT_EXIT (SSL_ST_ACCEPT|SSL_CB_EXIT) - -=item SSL_CB_CONNECT_LOOP (SSL_ST_CONNECT|SSL_CB_LOOP) - -=item SSL_CB_CONNECT_EXIT (SSL_ST_CONNECT|SSL_CB_EXIT) - -=item SSL_CB_HANDSHAKE_START - -Callback has been called because a new handshake is started. - -=item SSL_CB_HANDSHAKE_DONE 0x20 - -Callback has been called because a handshake is finished. - -=back - -The current state information can be obtained using the -L family of functions. - -The B information can be evaluated using the -L family of functions. - -=head1 RETURN VALUES - -SSL_set_info_callback() does not provide diagnostic information. - -SSL_get_info_callback() returns the current setting. - -=head1 EXAMPLES - -The following example callback function prints state strings, information -about alerts being handled and error messages to the B BIO. - - void apps_ssl_info_callback(SSL *s, int where, int ret) - { - const char *str; - int w; - - w=where& ~SSL_ST_MASK; - - if (w & SSL_ST_CONNECT) str="SSL_connect"; - else if (w & SSL_ST_ACCEPT) str="SSL_accept"; - else str="undefined"; - - if (where & SSL_CB_LOOP) - { - BIO_printf(bio_err,"%s:%s\n",str,SSL_state_string_long(s)); - } - else if (where & SSL_CB_ALERT) - { - str=(where & SSL_CB_READ)?"read":"write"; - BIO_printf(bio_err,"SSL3 alert %s:%s:%s\n", - str, - SSL_alert_type_string_long(ret), - SSL_alert_desc_string_long(ret)); - } - else if (where & SSL_CB_EXIT) - { - if (ret == 0) - BIO_printf(bio_err,"%s:failed in %s\n", - str,SSL_state_string_long(s)); - else if (ret < 0) - { - BIO_printf(bio_err,"%s:error in %s\n", - str,SSL_state_string_long(s)); - } - } - } - -=head1 SEE ALSO - -L, L, -L - -=cut -- cgit v1.3
