function marks the thread identified by
thread as detached. When a
detached thread terminates, its resources are automatically
released back to the system without the need for another
thread to join with the terminated thread.
Attempting to detach an already detached thread results in unspecified behavior.
For an explanation of the terms used in this section, see attributes(7).
Once a thread has been detached, it can't be joined with pthread_join(3) or be made joinable again.
The detached attribute merely determines the behavior of the system when the thread terminates; it does not prevent the thread from being terminated if the process terminates using exit(3) (or equivalently, if the main thread returns).
Either pthread_join(3) or
pthread_detach() should be
called for each thread that an application creates, so that
system resources for the thread can be released. (But note
that the resources of all threads are freed when the process
