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.

NAME
pthread_detach() - mark a thread as detached to reclaim its resources when it terminates SYNOPSIS
PARAMETERS
thread Thread whose resources are to be reclaimed immediately when it terminates. DESCRIPTION

If thread has already terminated, causes the resources of thread to be reclaimed by the system. does not cause thread to terminate. Once a detached thread has terminated, its resources, including the thread ID, may be reused by the system. The return status of a detached thread is lost when the thread terminates.

Upon successful completion, returns zero. Otherwise, an error number is returned to indicate the error (the variable is not set). ERRORS
If any of the following occur, the function returns the corresponding error number: [EINVAL] thread does not refer to a joinable thread. [ESRCH] No thread could be found corresponding to thread. AUTHOR
