Are you sure you have write permissions to that directory? (I notice
it's under /Applications, but it's also under xampp, so maybe you do,
but I don't know.) Is an exception printed to the console? Are you
sure fh is not nil?

Devon, thanks for your response. However, your suggestion still does
not make the code work. No data is written to the file.
/* WRITE DATA TO FILE: THIS IS A TEST */
[fh writeData:@"THIS IS A TEST"];
[fh closeFile];
I simply was copying the advice given on a previous post. I have
tried just about everything and can get nothing to work? has anyone
on this list ever had success in writing to a local file, and if so
can you show me the code you used?
Thanks,
Seth

NSFileHandle writeData takes an NSData pointer not a string
and that's
actually not how you do a string, you're missing the @
in front of it.

ORIGINAL MESSAGE:
I saw this post on the list previously.
However I am still unable to write to a file... I have tried
everything...
Here is my code for my main.m file. What am I missing?
I am running a Mac OS X 10.4.11 and editing with Xcode 2.2.1
HERE IS MY CODE FOR main.m:
#import <Cocoa/Cocoa.h>
int main(int argc, char *argv[]) {
/* Define what file to write to on local hard drive... */
NSString *fname="/Applications/xampp/xamppfiles/htdocs/data/
data.txt";
/* CREAT EMPTY FILE? */
[@"" writeToFile:fname atomically:NO];
NSFileHandle *fh=[NSFileHandle fileHandleForWritingAtPath:fname];
/* WRITE DATA TO FILE: THIS IS A TEST */
[fh writeData:"THIS IS A TEST"];
[fh closeFile];
return NSApplicationMain(argc, (const char **) argv);
}
/* end main.m */

Do you insist on this workflow?
In a vast majority of cases you just write the complete file
atomically, like
NSData *d=... the contents of file computed somehow ...
[d writeToFile:FILENAME atomically:YES];
Nevertheless, you can use NSFileHandle
NSString *fname=...;
[@"" writeToFile:fname atomically:NO]; // create the empty file
NSFileHandle *fh=[NSFileHandle fileHandleForWritingAtPath:fname];
...
[fh writeData:... partial contents of file computed somehow ...]; //
as many times as you want to
...
[fh closeFile];
