pthread_detach - detach a thread
#include <pthread.h> int pthread_detach(pthread_t thread);
Compile and link with
The pthread_detach() 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.
On success, pthread_detach() returns 0; on error, it returns an error number.
The following statement detaches the calling thread:
thread is not a joinable thread.
No thread with the ID
thread could be found.
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 any threads for which one of these actions has not been done will be freed when the process terminates.)
