pthread_detach(3C) Standard C Library Functions pthread_detach(3C) NAME
pthread_detach - detach a thread SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_detach(pthread_t thread); DESCRIPTION
The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when that thread terminates. In other words, pthread_detach() dynamically resets the detachstate attribute of the thread to PTHREAD_CRE- ATE_DETACHED. After a successful call to this function, it would not be necessary to reclaim the thread using pthread_join(). See pthread_join(3C). If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on the same target thread is unspecified. RETURN VALUES
If successful, pthread_detach() returns 0. Otherwise, an error number is returned to indicate the error. ERRORS
The pthread_detach() function will fail if: EINVAL The implementation has detected that the value specified by thread does not refer to a joinable thread. ESRCH No thread could be found corresponding to that specified by the given thread ID. ATTRIBUTES

PTHREAD_DETACH(3) Linux Programmer's Manual PTHREAD_DETACH(3) NAME
pthread_detach - detach a thread SYNOPSIS
#include <pthread.h> int pthread_detach(pthread_t thread); Compile and link with -pthread. DESCRIPTION
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. RETURN VALUE
On success, pthread_detach() returns 0; on error, it returns an error number. ERRORS
EINVAL thread is not a joinable thread. ESRCH No thread with the ID thread could be found. CONFORMING TO
POSIX.1-2001. NOTES
Once a thread has been detached, it can't be joined with pthread_join(3) or be made joinable again. A new thread can be created in a detached state using pthread_attr_setdetachstate(3) to set the detached attribute of the attr argument of pthread_create(3). 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 terminates.) EXAMPLE
The following statement detaches the calling thread: pthread_detach(pthread_self()); SEE ALSO
