Hi Netland,
I have a question for all you fellow techies. I would like to
create my own MsgPort via the Exec. However, I want to do it in assembler
I know that the CreatePort() function exists, but only in the link
library. (ie. it's not a REAL rom routine.) So, I am trying to get
its equivalent. I am currently doing something like the following:
1) Allocate a hunk of memory MP_SIZE big.
2) set the LN_NAME to point to my name.
3) set the LN_PRI to 0
4) Call AddPort()
I >THINK< this is the correct way of going about it. However I'm not
sure, and I don't have an Exec manual handy for the source to
CreatePort(), and this part of the code is a strong suspect for a
bug that I have.
What I'd like is one of the following:
a) confirmation that this method is right,
b) an example of how to do this (C or ASM), or
c) source to CreatePort() from the Exec manual
I really doubt c) is legal, so I'm not too concerned about that. a)
or b) would solve my problem just as well. ANY help/suggestions
would be appreciated! E-mail or post, as you feel appropriate.
Thanks in advance,
Greg Roberts II
