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_CREATE_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.
