Closing the terminal's output in exercise 16.7?

[dharma]

So, my question is, in the code I have:

Code: (Objective-C)

#import <Foundation/Foundation.h>

#define kBufSize 128

int main (int argc, const char * argv[]) {
	
	NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
	NSFileHandle *inFile, *outFile;
	NSData *buffer;
	
	inFile = [NSFileHandle fileHandleForReadingAtPath:@"testfile"];
	
	if (inFile == nil)
	{
		NSLog(@"Open of testfile for reading failed!");
		return 1;
	}
	
	outFile = [NSFileHandle fileHandleWithStandardOutput];
		
	buffer = [inFile readDataOfLength: kBufSize];
	
	while (buffer.length != 0) {
		[outFile writeData: buffer];
		(buffer = [inFile readDataOfLength: kBufSize]);
	}
	
	[inFile closeFile];
	[outFile closeFile];
	
	[pool drain];
	return 0;}

Do we need to close outFile, since it isn't really a file but the terminal's output? (I should call it outToTerminal or something, I know )

It will be closed when the application terminates.  It's a good habit to get into anyway.   If it were a file, closing it would flush out any data pending to be written to the file.
