CreateMsgPort is deprecated?

I'm getting this warning while compiling my software. This function is deprecated. What am i supposed to replace it with???

AllocSysObjectTags( ASOT_PORT, tags...);

Check exec/exectags.h for tags to accompany it.

And use FreeSysObject() rather than DeleteMsgPort().

You'll usually be fine with:

Thanks guys.

@Antique

so, what way did you choose? the Rigo's way or trixie's way?

I am asking it as I am a newbie developer and I am just learning Reaction starting from the example and tutorial in the AmigaWiki Page..

@nubechecorre

It's the same way. My example uses no tags because that's what most port allocations are fine with. For example, if you just need to allocate a message port for the ReAction window.class, IExec->AllocSysObject(ASOT_PORT, NULL) is perfectly sufficient, as you can see in one of my tutorials over at OS4depot.net.

Rigo's example uses the same function call but with tags. You'd use tags, for example, if you needed a named message port. In this case you'd do something like

(Edited accordingly, based on Thomas' post below)
IExec->AllocSysObjectTags(ASOT_PORT, ASOPORT_Name, "MyNamedPort", TAG_DONE);

And... don't forget to call IExec->FreeSysObject() when you no longer need the port!

Quote:

This should read IExec->AllocSysObjectTags(ASOT_PORT, ASOPORT_Name, "MyNamedPort", TAG_DONE);

Otherwise it won't compile.

AllocSysObject takes a pointer to an array of struct TagItem, AllocSysObjectTags takes the tag items as varargs.

Of course! Sorry - a silly copy-and-paste mistake. Thank you for the correction, I'll edit the original post accordingly.

Another frequent use of the tags is when you want to use a structure that starts with a MsgPort, but all the rest of it is private stuff.
eg:
struct PostOffice
{
struct MsgPort;
APTR ---
---
---
};

You can allocate such a structure as a MsgPort of a larger size, using the tag
"ASOPORT_Size, sizeof (struct PostOffice)". You will then get a clean, initialised MsgPort and all the space after it that you need. You can simply FreeSysObject (ASOT_PORT, xxx) when you're finished with it.
