pthread_detach(3T) pthread_detach(3T)
Pthread Library
NAME
pthread_detach() - mark a thread as detached to reclaim its resources
when it terminates.
SYNOPSIS
#include <pthread.h>
int pthread_detach(
pthread_t thread
);
PARAMETERS
thread Thread whose resources are to be reclaimed immediately
when it terminates.
DESCRIPTION
pthread_detach() is used to detach the thread thread. When thread
terminates, its resources will automatically be reclaimed by the
system. If thread has already terminated, pthread_detach() causes the
resources of thread to be reclaimed by the system.
pthread_detach() 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.
Calling this function multiple times for the same thread results in
undefined behavior.
RETURN VALUE
Upon successful completion, pthread_detach() returns zero. Otherwise,
an error number is returned to indicate the error (the errno variable
is not set).
ERRORS
If any of the following occur, the pthread_detach() function returns
the corresponding error number:
[EINVAL] thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to thread.
