iv_fatal(3) ivykis programmer's manual iv_fatal(3)NAME
iv_fatal, iv_set_fatal_msg_handler - ivykis fatal error condition handling
void iv_fatal(const char *fmt, ...);
void iv_set_fatal_msg_handler(void (*handler)(const char *msg));
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.

iv_thread_create, iv_thread_set_debug_state - ivykis thread convenience functions
int iv_thread_create(char *name, void (*start_routine)(void *), void *arg);
void iv_thread_set_debug_state(int state);
iv_thread_create is a wrapper around pthread_create(3) which will maintain an ivykis main loop reference in the calling thread (which must
be an ivykis(3) thread, i.e. have had iv_init(3) called in it) for as long as the created thread is alive.
Maintaining a reference on the calling thread's ivykis event loop makes sure that the calling thread will not return from its ivykis main
loop before the created thread exits, as that could cause cleanup still happening in the created thread to be interrupted when the calling
thread subsequently calls exit(3).
The created thread need not be an ivykis thread.
Enabling debugging by calling iv_thread_set_debug with a nonzero argument will print a debug message to standard error whenever a thread is
created via iv_thread_create, whenever a thread so created terminates normally by returning from its start_routine, self-terminates by
calling pthread_exit(3), or is successfully canceled by pthread_cancel(3), and whenever destruction of such a thread is signaled back to
the calling thread.
For inter-thread signaling, iv_thread uses iv_event(3).
