.\"set the default error message to a specified string .TH notify_fail 3 "5 Sep 1994" MudOS "LPC Library Functions" .SH NAME int notify_fail( string | function str ); .SH DESCRIPTION Store `str' as the error message to be returned instead of the default message `What?'. The message will be displayed if a 0 is returned from an action setup via add_action(). This is the preferred way to display error messages since it allows other objects a chance to respond to the same verb (command). Do not use write() to display the error message since this will require you to return a 1 (unless you want to see the result of the write() in addition to the 'What?' message). However, if you do return a 1, then no other objects will get a chance to respond to the user command. If a function is passed instead of a string, the function is called instead of printing a message. If the function returns a string, that string is used as the failure message. Also, this_player() is set correctly, so write() can be used. .PP If "notify_fail()" is called more than once, only the last call will have an effect. .PP The idea behind this function is to allow better error messages than `What?'. .SH RETURN VALUE notify_fail() always returns 0.
