# PRThread

An NSPR thread.

## Syntax

```{code}
#include <prthread.h>

typedef struct PRThread PRThread;
```

### Description

In NSPR, a thread is represented by a pointer to an opaque structure of
type {ref}`PRThread`. This pointer is a required parameter for most of the
functions that operate on threads.

A `PRThread*` is the successful result of creating a new thread. The
identifier remains valid until it returns from its root function and, if
the thread was created joinable, is joined.
