<h2>Thread ID value and size</h2>
|
|
|
|
<p>In some threads implementations, the thread ID is a 4-byte integer that
|
|
starts at 1 and increases by 1 every time a thread is created. This integer can
|
|
be used in a non-portable fashion by an application.</p>
|
|
|
|
<p>To assist in the portability problem with the application and to allow
|
|
retrieval of the thread ID, the iSeries implementation has provided the <strong>
|
|
pthread_getunique_np</strong>() function to retrieve the thread ID from the
|
|
Pthread handle. This thread ID is a 64-bit integer value. Because some
|
|
compilers do not yet support a full 64-bit integer data type, the value is
|
|
returned in a structure containing two 4-byte integers.</p>
