# SbThreadAutoLock Class Reference
[Portable thread-handling abstractions]

`#include <Inventor/threads/SbThreadAutoLock.h>`

List of all members.

## Detailed Description

Simple convenience class for locking access to a function.

This class provides a simple convenience mechanism for automatically locking access to a function that is not re-entrant.

Usage example:

      void
      myfunction(void)
      {
        SbThreadAutoLock lock(aMutexPtr);

        // [other code]
      }

In the class constructor, SbMutex::lock() is called on the mutex, and when the function exits (this is the convenience part) the destructor will automatically be invoked, calling SbMutex::unlock() on the same mutex.

## Public Member Functions

## Constructor & Destructor Documentation

SbThreadAutoLock::SbThreadAutoLock | ( | SbMutex * | mutex | ) | `[inline]`

| The constructor calls SbMutex::lock() on mutex.

SbThreadAutoLock::~SbThreadAutoLock | ( |  | ) | `[inline]`

| The destructor calls SbMutex::unlock() on the mutex passed in as a parameter to the constructor.

## Member Data Documentation

SbThreadAutoLock::mutex `[protected]`

| This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
