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.
