I am sure, someone has already solved the following problem: For an implementation of un*x fstat(), i have to do an Examine() on a filehandle (NOT a struct FileLock *). So how can I convert filehandles to filelocks (under AmigaDOS 1.3) or examine the properties of a file associated to a filehandle directly ? (BTW: just for motivation of answers: I nearly succeded in compiling the BSD 4.3 c library for Gnu cc, one of the missing functions is fstat() ...)

Under 2.0, you can just use ExamineFH(). Under 1.3, it can't be done. Period. Sorry. (This is why there's now an ExamineFH()...) If you can somehow remember the string used to open it, you can get the info that way (Lock() it and examine, but that will fail if the ope is exclusive, or strip the last portion of the path, lock the parent, and then ExNext through the parent until you come to the file. That works even if the file is exclusively locked.) -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.commodore.com BIX: rjesup The compiler runs Like a swift-flowing river I wait in silence.

I have a question, which is hard to explain, but perhaps easy to answer. I have a program which updates info on the screen every second. Its exitable by clicking on the close gadget of its window. Currently I am delaying by Delay(60) and then checking the windows message port for a message, outputting my info, then looping back to the Delay. The problem is, if the user clicks on the close gadget, it could be a second before the program responds (since its in a delay) and hence if I move the delay up, which I want to...then it could be 5secs or more before the window closes. So the basic idea is, how can I start a timed event that will pump a signal to me when it completes, so that I can have the program waiting for a signal from that timer or from the window message port...hence if the user clicks on the close gadget, it immediately can respond ? Assembly or C answers.... Thanks, Robert Lang.

Hello,
I am writing a function/scientific plotting program, and I am trying to
make it work in many different environments. I am making it configurable
for PAL, NTSC, 1.3, 2.0 & ECS (screen resolutions), and hopefully A2024.
There are several things I would like to know about the A2024 monitor:
The resolution is 1008 x 800 (2 bitplanes), but is the A2024 in Europe
(A2025 ???) a PAL monitor with 1008 x 1024 ?
It is the same as a Moniterm Viking I monitor (in the way the system
drives the video)?
Assuming that someone has a A2024 (or a Moniterm) with 1.3, how does a
C programmer get a 1008 x 800 screen open. I vaugely remember something
about Intuition.library V35 being the version that would allow the A2024
to operate. What flags go into the new_screen.Flags field?
How do I open the 1008 x 800 screen under 2.0 ?
Any help along these lines would be greatly appreciated as I am trying to
support a device that I have never seen!
Thanks in advance,
Dale Hollenbaugh

Yes, NTSC 2024 (60Hz) = 1008 x 800; PAL 2024 (50Hz) = 1008 x 1024. >It is the same as a Moniterm Viking I monitor (in the way the system >drives the video)? Yes, the moniterm and the 2024 are the same thing, one has the decoding stuff in the monitor and one requires a video card. The tube size is different as well. >Assuming that someone has a A2024 (or a Moniterm) with 1.3, how does a >C programmer get a 1008 x 800 screen open. I vaugely remember something >about Intuition.library V35 being the version that would allow the A2024 >to operate. What flags go into the new_screen.Flags field? You must use tags to do this. Under V35 you can set the NS_EXTENDED bit and call OpenScreen(). For V36 and later you can call OpenScreenTags() or OpenScreenTagList(). It looks like you need to set (in addition to the regular stuff): #include <graphics/view.h> #include <intuition/screens.h> /* struct ExtNewScreen is struct NewScreen with the ** following field added to the end: ** ** struct TagItem *Extension; */ struct ExtNewScreen newscreen; /* this tag must be first for V35 compatibility. */ taglist[0].ti_Tag = NSTAG_EXT_VPMODE; taglist[0].ti_Data = VPF_A2024 | VPF_TENHZ; /* or just VPF_A2024 */ taglist[1].ti_Tag = TAG_END; if (GfxBase->LibNode.lib_Version <= 34) ; /* can't do tags or moniterm */ else if (GfxBase->LibNode.lib_Version == 35) { newscreen.extension = taglist; newscreen.Type = CUSTOMSCREEN | NS_EXTENDED; newscreen.ViewModes = 0; /* for 2024 */ newscreen.Width = 1008; newscreen.Height = 800; if (GfxBase->DisplayFlags & PAL) newscreen.Height = 1024; if (NULL != (screen = OpenScreen(&newscreen))) { /* succeeded! */ } } else if (GfxBase->LibNode.lib_Version >= 36) ; /* see AmigaMail article, described below. */ >How do I open the 1008 x 800 screen under 2.0 ? Same way, but you must check the display database to see if the mode is available.

If you have the new ECS agnus that has the expanded blit ranges you can use 1024x800 and 1024x1024! To use 1024x800 instead of 1008x800 all you have to do is specify the new width in the NewScreen structure. I wonder if the graphics will work if I specify 2048x800 and use RasInfo->RxOffset to ping pong left and right? >Ken Farinsky - CATS - (215) 431-9421 - Commodore Business Machines -- Dale Luck GfxBase/Boing, Inc. {uunet!cbmvax|pyramid}!amiga!boing!dale

Is there a software called LATEX on AMIGA ? Where could I find it? And at which prize?
