File Objects Routines

Reading and Writing File Data

QuickDraw 3D provides routines that you can use to access custom data in a file object. In all cases, the reading or writing occurs at the current file position, and the file position is advanced if the read or write operation completes successfully.

IMPORTANT

You should call the _Read functions only in a custom read data method (of type kQ3MethodTypeObjectReadData), and you should call the _Write functions only in a custom write method (of type kQ3MethodTypeObjectWrite).

These functions can read and write data in either text or binary files.
