Code: (Objective-C)

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSFileHandle *inFile, *outFile;
NSData *buffer;

// Open the file fileA for reading

inFile = [NSFileHandle fileHandleForReadingAtPath: @"fileA"];

if (inFile == nil)
NSLog(@"Open of fileA for reading failed!");
return 1;

// Now  open outfikle for writing

outFile = [NSFileHandle fileHandleForWritingAtPath: @"fileB"];

if (outFile == nil)
NSLog(@" open of fileB for writing failed!");
return 2;

// seek to end of  outfile
[outFile seekToEndOfFile];

// read infile and write its content to outfile

buffer = [ inFile readDataToEndOfFile];
[outFile writeData: buffer];

//close the two files

[inFile closeFile];
[outFile closeFile];

// verify its contents

NSLog(@"%@", [NSString stringWithContentsOfFile: @"FileB"
encoding: NSUTF8StringEncoding error: NULL]);

[pool drain];
    return 0;
