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

NAME
       iv_fatal, iv_set_fatal_msg_handler - ivykis fatal error condition
       handling

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
       message 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.
