| typedef int(* tfTelnetConnect)(tsTelnetConn *telnetconn) |
This application supplied callback function is called each time a telnet client connects to the telnet server. This function MUST be specified in tsTelnetdParams::connect_func field passed to tcTelnetd::run().
| telnetconn | The connection structure for the new connection. Typically your application would set the tsTelnetConn::user2 field during execution of this callback if you have application specific data which you will reference in the future. |
| typedef int(* tfTelnetChkUser)(tsTelnetConn *telnetconn, const char *user) |
This application supplied callback function is called each time a telnet client enters a username during connection login. This function may optionally be specified in tsTelnetdParams::chk_user_func field passed to tcTelnetd::run(). If the tsTelnetdParams::chk_user_func field is set to NULL, then no user name verification will be performed.
| telnetconn | The connection structure for the connection. |
| user | The user name from the telnet client. |
| typedef int(* tfTelnetChkPswd)(tsTelnetConn *telnetconn, const char *pswd) |
This application supplied callback function is called each time a telnet client enters a password during connection login. This function may optionally be specified in tsTelnetdParams::chk_pswd_func field passed to tcTelnetd::run(). If the tsTelnetdParams::chk_pswd_func field is set to NULL, then no password verification will be performed.
| telnetconn | The connection structure for the connection. |
| password | The password from the telnet client. |
| typedef void(* tfTelnetClose)(tsTelnetConn *telnetconn) |
This application supplied callback function is called each time a telnet connection is closed. This function may optionally be specified in tsTelnetdParams::close_func field passed to tcTelnetd::run(). If the tsTelnetdParams::close_func field is set to NULL, then no close notification will be generated.
| telnetconn | The connection structure for the connection. |
| typedef int(* tfTelnetInChar)(tsTelnetConn *telnetconn, char c) |
This application supplied callback function is called each time a telnet client sends a character. This function MUST be specified in tsTelnetdParams::in_char_func field passed to tcTelnetd::run().
| telnetconn | The connection structure for the connection. |
| typedef bool(* tfTelnetHandleOption)(tsTelnetConn *telnetconn, unsigned char cmd, unsigned char opt) |
This application supplied callback function is called whenever an RFC 854 Option Request is received.
| telnetconn | The connection structure for the connection. |
| cmd | command option (WILL, WONT, DO, DONT) |
| option | code requested |
| typedef bool(* tfTelnetHandleCmd)(tsTelnetConn *telnetconn, unsigned char cmd) |
This application supplied callback function is called whenever an RFC 854 Command is received
| telnetconn | The connection structure for the connection. |
| cmd | command (NOP, DM, BRK, IP, AO, AYT, EC, EL, GA) |
| typedef bool(* tfTelnetHandleSubNeg)(tsTelnetConn *telnetconn, unsigned char *NegStream, int StreamLen) |
This application supplied callback function is called whenever an RFC 854 Subnegotiation sequence is received.
| telnetconn | The connection structure for the connection. |
| NegStream | negotiation stream (without SB or SE character) |
| StreamLen | length of negotiation stream |
| typedef struct _tsTelnetdParams tsTelnetdParams |
This structure specifies the application callback functions which the telnet server will call during execution. You will also specify the tsTelnetConn::user1 parameter which you may access during callback function execution.
