Re: Newbie Apple question - FSRead

It is okay to call FSRead a byte at a time.

As for being buffered, I don't know what happens internally, but I've always treated FSRead as unbuffered. I expect that the hardware reads a sector at a time so no matter what the buffering scheme a 1-2 KB file is likely loaded with the first read.

Bottom line: don't worry about the buffering. I doubt that you're going to get much noticeable performance bonus by tweaking the reads of small configuration files.

There's a list for carbon development:

I am writing a Carbon application that reads some relatively small (1-2K)
configuration files.

Is it OK to call FSRead to get a byte at a time?. I guess the question
really is: Is FSRead internally buffered? Or am I double-buffering by
creating my own buffering loop to keep from calling FSRead() several
thousand times.

Thanks
