PTHREAD_DETACH(3) BSD Library Functions Manual PTHREAD_DETACH(3)NAMEpthread_detach — detach a thread
POSIX Threads Library (libpthread, -lpthread)
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. 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!
The pthread_detach() function 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.
The pthread_detach() function conforms to ISO/IEC 9945-1:1996
