pthread_detach -- detach a thread
#include <pthread.h> int pthread_detach(pthread_t thread);
The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when the thread ter- minates. 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 pthread_detach() function will return zero. Other- wise, 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: [EINVAL] The implementation has detected that the value speci- fied by thread does not refer to a joinable thread. [ESRCH] No thread could be found corresponding to that speci- fied by the given thread ID, thread.
pthread_detach() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD April 4, 1996 BSD
