passing arguments to a CreateNewProc process....etc.

[Piru]

can't find NP_UserData tag Dietmar mentioned anywhere. I was supposing it's a tag for CreateNewProc() ? Is it an AOS3.9 only thing?

It's AROS/MorphOS thing. AmigaOS 3.x doesn't have it. No clue if AmigaOS 4 copied it.

I was also about to use the process own port but the RKM's advise against using it, saying it's for exclusively use by DOS. I guess if I use it only in the beginning before using any dos function I'll be alright?

Exactly.

Anyway, I'd prefer that NP_UserData tag, it's more practical

Too bad it's AROS/MorphOS thing.

-EDIT- MorphOS actually interherited the tag from AROS :-)

I wouldn't bet about that ;-) (hint hint!)

Ahhh....Shame on 3.x for not having it... I'll use (struct Process *)->pr_MsgPort then...

[EDIT]

Actually I fell more tempted to poke tc_UserData.. :-)

@falemagn

Oh, hehe. Right :-)

Anyway, the tag rules indeed. You get rid of that nasty sync/poking crap. Nice idea.

Hi,

@Jose

Depending on the kind of data you want to pass you may pass them as string using NP_Arguments.
Poking tc_UserData is not much better code than using global variables in my opinion. Using messages protects from race conditions resp. you don't have to use Forbid()/Permit() (which should be avoided when ever possible).

How is NP_UserData defined?
