Chapter 10 Multimedia File I/O Services

Most multimedia applications require file I/O—the ability to create, read, and write disk files. Multimedia file I/O services provide buffered and unbuffered file I/O, and support for standard IBM/Microsoft Resource Interchange File Format (RIFF) files. The services are extensible with custom I/O procedures that can be shared among applications.

This chapter covers the following topics:

Using basic file I/O services

Performing buffered file I/O

Working with RIFF files

Directly accessing a file I/O buffer

Using memory files

Writing a custom I/O procedure

Note:

The Multimedia file I/O services will provide support for RIFF compound files in a future release of the Multimedia extensions.
