NAME

get_char  -  causes  next  character of input to be sent to a specified
function

SYNOPSIS

varargs void get_char( string | function fun, int flag, ... );

DESCRIPTION

Enable next character of user input to be sent to the function 'fun' as
an argument. The input character will not be parsed by the driver.

Note  that get_char is non-blocking which means that the object calling
get_char does not pause waiting for input.  Instead the object  contin‐
ues  to  execute  any statements following the get_char.  The specified
function

If "get_char()" is called more than once in the  same  execution,  only
the first call has any effect.

If  optional  argument 'flag' is non-zero, the char given by the player
will not be echoed, and is not seen if snooped (this is useful for col‐
lecting passwords).

The  function  'fun'  will  be  called with the user input as its first
argument (a string). Any additional arguments supplied to get_char will
be passed on to

BUGS

Please  note  that get_char has a significant bug in MudOS 0.9 and ear‐
lier.  On many systems with poor telnet negotiation (read: almost every
major  workstation  on the market), get_char makes screen output behave
strangely.  It is not  recommended  for  common  usage  throughout  the
mudlib  until  that  bug is fixed.  (It is currently only known to work
well for users connecting from NeXT computers.)
