PR_AttachThread

« NSPR API Reference « Threads

Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Associates a PRThread object with an existing native thread.

Syntax

#include <pprthread.h>

PRThread* PR_AttachThread(
   PRThreadType type,
   PRThreadPriority priority,
   PRThreadStack *stack);

Parameters

PR_AttachThread has the following parameters:

type
Specifies that the thread is either a user thread (PR_USER_THREAD) or a system thread (PR_SYSTEM_THREAD).
priority
The priority to assign to the thread being attached.
stack
The stack for the thread being attached.

Returns

The function returns one of these values:

  • If successful, a pointer to a PRThread object.
  • If unsuccessful, for example if system resources are not available, NULL.

Description

You use PR_AttachThread when you want to use NSS functions on the native thread that was not created with NSPR. PR_AttachThread informs NSPR about the new thread by associating a PRThread object with the native thread.

The thread object is automatically destroyed when it is no longer needed.

You don't need to call PR_AttachThread unless you create your own native thread. PR_Init calls PR_AttachThread automatically for the primordial thread.

Note: As of NSPR release v3.0, PR_AttachThread and PR_DetachThread are obsolete. A native thread not created by NSPR is automatically attached the first time it calls an NSPR function, and automatically detached when it exits.

In NSPR release 19980529B and earlier, it is necessary for a native thread not created by NSPR to call PR_AttachThread before it calls any NSPR functions, and call PR_DetachThread when it is done calling NSPR functions.
