Re: [hatari-devel] A question about the debugger

Hi,

(I'll look at the other issues you mentioned later,
I just wanted to answer this first.)

Hatari developers don't have/use Windows, and as your issues are
new to us, I guess you're unfortunately spearheading the debugger
logging usage there...

It has to.  Autostarting is implemented by providing an autogenerated
DESKTOP.INF (or EMUDESK.INF) file which tells TOS to start
that application.

Hatari has no way to guess what path depth you want, so it just
assumes that program works fine when GEMDOS drive is pointed
at the autostarted program directory.  99% of them do work fine.

Windows crappiness.  The standard C tmpfile() function doesn't
return on your system a writable file / name.

According to MSDN, this seems to require root dir to be writable:
https://msdn.microsoft.com/en-us/library/x8x7sakw.aspx

Btw. That same page recommends using tmpnam() or tempnam()
if one wants version that creates the temporary file
somewhere else, but Linux documentation states on those:
"POSIX.1-2008 marks this function as obsolete.
Never use this function.  Use mkstemp(3) or tmpfile(3) instead."

However, mkstemp() isn't portable (it's POSIX, not ANSI-C function),
so Hatari picked tmpfile().

Ps. This isn't first standard C function where we've found
Windows to be crap (after user complaints).
