-.SH NAME
-pthread_detach \- detach a thread
-.SH LIBRARY
-POSIX threads library
-.RI ( libpthread ", " \-lpthread )
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-.P
-.BI "int pthread_detach(pthread_t " thread );
-.fi
-.SH DESCRIPTION
-The
-.BR pthread_detach ()
-function marks the thread identified by
-.I 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.
-.P
-Attempting to detach an already detached thread results
-in unspecified behavior.
-.SH RETURN VALUE
-On success,
-.BR pthread_detach ()
-returns 0;
-on error, it returns an error number.
-.SH ERRORS
-.TP
-.B EINVAL
-.I thread
-is not a joinable thread.
-.TP
-.B ESRCH
-No thread with the ID
-.I thread
-could be found.
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
-.BR attributes (7).
-.TS

-lbx lb lb

-.SH STANDARDS
-POSIX.1-2008.
-.SH HISTORY
-POSIX.1-2001.
-.SH NOTES
-Once a thread has been detached, it can't be joined with
-.BR pthread_join (3)
-or be made joinable again.
-.P
-A new thread can be created in a detached state using
-.BR pthread_attr_setdetachstate (3)
-to set the detached attribute of the
-.I attr
-argument of
-.BR pthread_create (3).
-.P
-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
-.BR exit (3)
-(or equivalently, if the main thread returns).
-.P
-Either
-.BR pthread_join (3)
-or
-.BR 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.)
-.SH EXAMPLES
-The following statement detaches the calling thread:
-.P
-.in +4n
-.EX
-pthread_detach(pthread_self());
-.EE
-.in
