Hi Networkers,
This is the third part of my adventures with OS/2... I asked you
yesterday about a way to access files on an HPFS disk with IBM C/2. I've
been answered to:
- define PROTMODE in my .DEF file used at link time or
- change the header with exehdr or another tools.
Here are the results:
- PROTMODE has no effect, except changing the value of the bytes at
offset 88H and 8Ch.
- I don't have either exehfr ot the other tool.
So, I still have a SYS1943: A program caused a protection violation when
I try to open a file whose name is DEBUG.TEST on my HPFS disk with fopen.
HELP !!!! What have done that is wrong ? What am I supposed to install ?
Paul.

I also suggested you could use the DEF file to set the long names attribute; if you don't have exehdr (are you sure?), then use the def file line: NAME test NEWFILES This assumes you have a new enough version of the linker to support HPFS attributes. >So, I still have a SYS1943: A program caused a protection violation when >I try to open a file whose name is DEBUG.TEST on my HPFS disk with fopen. I don't know why it should cause a protection violation. Maybe you have an old library that doesn't understand HPFS (I wonder if it tries to copy the filename?)

I pulled this from the help I got when I typed LINK /HELP, looked at the command options, then Name Application Type, then another submenu, the NAME statement. Hope that this helps..

The sys... message is not a regular hardware style protection violation. It sounds more like file protection. Maybe it is a read only file that is opened for write, or something similar. Or maybe it just thinks it is. --- glen
