iv_fatal(3)		  ivykis programmer's manual		   iv_fatal(3)

NAME
       iv_fatal,  iv_set_fatal_msg_handler - ivykis fatal error	condition han-
       dling

SYNOPSIS
       #include	<iv.h>

       void iv_fatal(const char	*fmt, ...);
       void iv_set_fatal_msg_handler(void (*handler)(const char	*msg));

DESCRIPTION
       iv_fatal	aborts the running program, after possibly emitting  an	 error
       message.	The fmt	parameter is a printf(3)-style format string, the mes-
       sage to be logged.

       If no handler is	set (the default), the formatted message will be  sent
       to  syslog,  with  critical  severity.  Otherwise the handler as	set by
       iv_set_fatal_msg_handler	will be	used instead.

       iv_fatal	is also	used internally	by ivykis, whenever a fatal  situation
       is detected.

       iv_set_fatal_msg_handler	 can be	used to	set an alternative (as opposed
       to syslog) function to call from	iv_fatal, and its argument should be a
       function	 that does not return, and takes a single string as argument -
       the formatted error message.
