Hi !
I run into troubles with fopen() when I try to append to a textfile.
1) There are 2 different kinds of textfiles:
a) Textfiles WITH EOF character ( ^Z, 0x1A).
b) Textfiles WITHOUT EOF character.
Dont ask me why, that is MS-DOS...
2) If I use type b) files -> anything is fine.
If I try to use fopen(filename, "a") on a type a) file
fprintf() or any other of the output functions will write
BEHIND the EOF character. When opening such a file with an
editor (or any DOS-command) it will detect the EOF and the text
behind (which is actually there) cannot be accessed.
3) Workaround:
f = fopen(filename, "a");
fseek(f, -1, 1);
if(fgetc(f) == EOF)
fseek(f, -1, 1);
This would deal with both kinds of textfiles.
Is that a feature or a bug ?
Maybe it has been discussed before, but I have been removed from the list
several times (see below).

BTW:
I detected this morning, that I have been removed from the mailing list again.
It was the 3rd time since 1/1/94.
To all who dont believe:
1) I got no message that I have been removed.
2) there were no messages from this list for 5 days.
3) detection method:
I sent a delete message to listserv TODAY and got the following reply:
>> Per your request
>> "delete ahelm AT email DOT tuwien DOT ac DOT at djgpp"
>> 'ahelm AT email DOT tuwien DOT ac DOT at' was NOT FOUND on the 'djgpp' mailing list.
