Although it may still work in some 8 browsers, its use is discouraged since it could be removed at any 9 time. Try to avoid using it. 10 11Associates a :ref:`PRThread` object with an existing native thread. 12 13 14Syntax 15------ 16 17.. code:: eval 18 19 #include <pprthread.h> 20 21 PRThread* PR_AttachThread( 22 PRThreadType type, 23 PRThreadPriority priority, 24 PRThreadStack *stack); 25 26 27Parameters 28~~~~~~~~~~ 29 30:ref:`PR_AttachThread` has the following parameters: 31 32``type`` 33 Specifies that the thread is either a user thread 34 (``PR_USER_THREAD``) or a system thread (``PR_SYSTEM_THREAD``). 35``priority`` 36 The priority to assign to the thread being attached. 37``stack`` 38 The stack for the thread being attached. 39 40 41Returns 42~~~~~~~ 43 44The function returns one of these values: 45 46- If successful, a pointer to a :ref:`PRThread` object. 47- If unsuccessful, for example if system resources are not available, 48 ``NULL``. 49 50 51Description 52----------- 53 54You use :ref:`PR_AttachThread` when you want to use NSS functions on the 55native thread that was not created with NSPR. :ref:`PR_AttachThread` 56informs NSPR about the new thread by associating a :ref:`PRThread` object 57with the native thread. 58 59The thread object is automatically destroyed when it is no longer 60needed. 61 62You don't need to call :ref:`PR_AttachThread` unless you create your own 63native thread. :ref:`PR_Init` calls :ref:`PR_AttachThread` automatically for 64the primordial thread. 65 66.. note:: 67 68 **Note**: As of NSPR release v3.0, :ref:`PR_AttachThread` and 69 :ref:`PR_DetachThread` are obsolete. A native thread not created by NSPR 70 is automatically attached the first time it calls an NSPR function, 71 and automatically detached when it exits. 72 73In NSPR release 19980529B and earlier, it is necessary for a native 74thread not created by NSPR to call :ref:`PR_AttachThread` before it calls 75any NSPR functions, and call :ref:`PR_DetachThread` when it is done calling 76NSPR functions. 77
