| SYNOPSIS |
| #include <sys/driver_hooks.h> |
| |
| set_driver_hook(H_TELNET_NEG, value) |
| |
| <value> being: |
| |
| void <name>(int flag, object user, int no_telnet) |
| void <closure>(int flag, object user, int no_telnet) |
| |
| DESCRIPTION |
| Optional hook to specifiy how to perform the telnet actions to |
| switch the echo mode (used for e.g. password input_to()s). |
| Hook setting may be any closure or a string. If not set, a |
| default handling is performed. |
| |
| If the setting is a string, it is used as name of an lfun to call |
| in the interactive <user>, where <flag> is the echo-flag |
| passed to the input_to() statement. |
| |
| If the setting is a closure, it is called with the same |
| arguments, and unbound lambda-closures being bound to |
| this_player() prior to execution. |
| |
| <local> is a boolean flag: it is TRUE when input_to() was |
| called with the INPUT_NO_TELNET flag. |
| |
| When set, the hook is called whenever the driver needs to |
| change the echo mode, thus you can negotiate about things that |
| are coupled with it, like LINEMODE or character-at-a-time. |
| |
| IMPORTANT: If this hook is used, the control of all telnet |
| negotiation is transferred to the mudlib: all incoming negotiations |
| are passed to H_TELNET_NEG, and the sending of no-echo negotiations |
| is handled by this hook. |
| |
| HISTORY |
| LDMud 3.2.11/LDMud 3.3.593 added the <no_telnet> argument. |
