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.
