|
.Sh SYNOPSIS
|
|
.In 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!
|
|

|
|
.Fn pthread_detach
|
|
will fail if:
|
|
.Bl -tag -width Er

|
|
