<h1 class="topictitle1">Thread attributes</h1>
|
||
|
|
<div><p>Thread attributes are thread characteristics that affect the behavior
|
||
|
|
of the thread. Different attributes are available depending on the programming
|
||
|
|
language and API set that you are using.</p>
|
||
|
|
<div class="section"><p>Methods for using an attribute and its effect on the thread depend
|
||
|
|
on how the programming language and API set externalize the thread attribute
|
||
|
|
to your application. You can set the thread attributes at the time you start
|
||
|
|
a thread or change them after the thread is actively running.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><div class="p">Some common thread attributes and their effects are as follows: <ul><li>Priority:<p>The priority attribute affects the amount of processing time
|
||
|
|
that the system gives the thread before letting another thread or process
|
||
|
|
interrupt it.</p>
|
||
|
|
</li>
|
||
|
|
<li>Stack size:<p>The stack size attribute affects the number of functions
|
||
|
|
that a thread can call before the thread fails due to insufficient stack space.</p>
|
||
|
|
</li>
|
||
|
|
<li>Name:<p>The name attribute affects the ability to debug or track the actions
|
||
|
|
of a thread through your application.</p>
|
||
|
|
</li>
|
||
|
|
<li>Thread group:<p>The thread group attribute affects the ability to easily
|
||
|
|
manage more than one thread at a time.</p>
|
||
|
|
</li>
|
||
|
|
<li>Detach state:<p>The detach state attribute affects how you reclaim or
|
||
|
|
leave active resources associated with a thread when a thread ends.</p>
|
||
|
|
</li>
|
||
|
|
<li>Scheduling policy:<p>The scheduling policy attribute affects how the threads
|
||
|
|
are scheduled within the system or within the application. This relates to
|
||
|
|
thread priority.</p>
|
||
|
|
</li>
|
||
|
|
<li>Inherit scheduling:<p>The inherit scheduling attribute affects how the
|
||
|
|
priority of the thread is determined by the system.</p>
|
||
|
|
