It depends on operating system. In case of Solaris your new thread might not even start before your application ends up.
The basic idea is that pointer your pass to pthread_create must eixsts at the moment you thread starts-up. And if you plan to use this data in this thread (otherwise why do you pass it?) you must guarantee that this data is not being destroyed while your thread is running. Usually people use prthread_join for this purpose.

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

NAME
iv_thread_create, iv_thread_set_debug_state - ivykis thread convenience functions SYNOPSIS
#include <iv_thread.h> int iv_thread_create(char *name, void (*start_routine)(void *), void *arg); void iv_thread_set_debug_state(int state); DESCRIPTION
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). SEE ALSO
ivykis(3), iv_event(3), exit(3), pthread_cancel(3), pthread_create(3), pthread_exit(3) ivykis 2010-09-13 iv_thread(3)
