.Nd detach a thread
|
|
.Sh SYNOPSIS
|
|
.Fd #include <pthread.h>
|
|
.Ft int
|
|
.Fn pthread_detach "pthread_t thread"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn pthread_detach
|
|
function is used to indicate to the implementation that storage for the
|
|
thread
|
|
.Fa thread
|
|
can be reclaimed when the thread terminates. If
|
|
.Fa thread
|
|
has not terminated,
|
|
.Fn pthread_detach
|
|
will not cause it to terminate. The effect of multiple
|
|
.Fn pthread_detach
|
|
calls on the same target thread is unspecified.
|
|
.Sh RETURN VALUES
|
|
If successful, the
|
|
.Fn 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!
|
|
.Sh ERRORS
|
|
.Fn pthread_detach
|
|
will fail if:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EINVAL
|
|
The implementation has detected that the value specified by
|
|
.Fa thread
|
|
does not refer to a joinable thread.
|
|
.It Bq Er ESRCH
|
|
No thread could be found corresponding to that specified by the given
|
|
thread ID,
|
|
.Fa thread .
