Hello.

I wrote about this problem already 2 weeks ago. I still have no solution
and the problem really seems to be with djgpp's 'fopen()' function!

fopen("test.txt", "r") returns NULL as long as I have this file
("test.txt") opened with MS Word for Windows. Other programs (emacs,
editor, notepad and DOS' type) have no problem reading the file!!! As
soon as I close the file (it's no longer opened with Word) then
fopen("test.txt", "r") works fine!

It seems there is some file-locking (sharing) mechanism with Win95 but
shouldn't it be possible to open the file for reading?????????

BTW:
- I use djgpp-v2 (gcc version 2.7.2.1) and run it in a DOS-box under
Windows95.
- I use emacs and have no such problems, but some people that use my
program would like to write the input-files (script-files) with Word ;-(
Some users (beginners) need to play around with my program which means
that they'd like to write e.g. 5 characters / save the file / run my
program and then make the next changes to the file. Just imagine the
amount of time it takes to CLOSE and then RE-OPEN the file with Word,
and they also need to find the correct line again...

I'D REALLY APRECHIATE VERY MUCH IF YOU COULD HELP ME!!!!!

Beni.
