detach a thread
function is used to indicate to the implementation that storage for the
thread thread can be reclaimed when the thread
terminates. 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.
If successful, the
function will return zero. Otherwise an error number will be returned to
indicate the error. Note that the function does not change the value of
errno as it did for some drafts of the standard. These
early drafts also passed a pointer to pthread_t as the argument. Beware!
pthread_detach() will fail if:
- The implementation has detected that the value specified by thread does not refer to a joinable thread.
- No thread could be found corresponding to that specified by the given thread ID, thread.
pthread_detach() conforms to
ISO/IEC 9945-1:1996 (“POSIX.1”).
