File Access Routines

This section describes the File Manager's file access routines. When you call one of these routines, you specify a file by a path reference number (which the File Manager returns to your application when your application opens the file). Unless your application has very specialized needs, you should be able to manage all file access (for example, writing data to the file) using the routines described in this section. Typically you use these routines to operate on a file's data fork, but in certain circumstances you might want to use them on a file's resource fork as well.
