|PTHREAD_DETACH(3)||Linux Programmer's Manual||PTHREAD_DETACH(3)|
int pthread_detach(pthread_t thread);
Compile and link with -pthread.
Attempting to detach an already detached thread results in unspecified behavior.
- thread is not a joinable thread.
- No thread with the ID thread could be found.
|pthread_detach ()||Thread safety||MT-Safe|
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.)
