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));
DESCRIPTIONiv_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.
