deprecated function in C++

Hello all,
I've came across an error I've never seen before in C++. I've started to experiment with OpenAL (because of problems with sdl mixer), I've installed the openal packages (.debs) however 3 functions report the above error.
For example warning: ‘alutUnloadWAV’ is deprecated. However I've no idea
what this means can anyone help. Thanks.

It means that the function will be removed in future versions of the library, and while you might be able to get your code working with it now, it may not build with future releases of openal.

When something is deprecated, it generally means a newer, better method of doing the same thing has been created, and you should use the new method.

In general, deprecated functions are those which are obsolete and being phased out of the project, but are included in the current release of a project for compatibility with older code.

Thanks guys

I can honestly say as someone whose worked as a programmer for more than a few years I've never seen that (well I might have and forgotten about it I'm getting old :s).

Be careful, you might be depreciated...

It's a situation that is more common to see in scripting languages where they bundle libraries and the language construct together.

If you ever want to deprecate your own function and you use gcc, place the following between the end of its declaration and ;:

Code:

__attribute__ ((deprecated))
