Here is the current code I am running:
This code has many fundamental errors. I think you need to review
the basics of the C language first, then of Objective-C. You have
to walk before you can run.
You say that you're not getting any errors or warnings when you
build this, but that can't be. You would definitely get warnings
for this code.
/* START CODE */
#import <Cocoa/Cocoa.h>
int main(int argc, char *argv[])
{
NSData *fname = "file:///Users/cknorr/mytest/MYTEST/data.txt";
You are initializing a variable of type NSData* (pointer to
NSData). However, the right-hand side is not an NSData*, it's a C-
style string, which is a character array (char* or char[]). These
are not compatible. It's certainly not meaningful. Any attempt to
use the fname variable as though it were a pointer to an NSData
object would fail, because it doesn't actually contain a valid
pointer to an NSData object.
NSFileHandle *fh=[NSFileHandle fileHandleForWritingAtPath:fname];
Even if fname did contain a valid pointer to an NSData object, the
above would not be correct. The +fileHandleForWritingAtPath: method
of NSFileHandle expects a pointer to an NSString object as its
argument, but that's not what you're providing.
and file:/// is a URL string, not a file system path.
