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.
