The MMIOOS2.H header file, supplied with the Toolkit, defines data structures used in passing information between an application and MMIO file services. Include the MMIOOS2.H file in any source that uses multimedia file I/O functions. Also include the main header file, OS2.H, which contains a declaration statement for the MMIOOS2.H file. The MMIOOS2.H file defines MMIO data structures listed in the following table.
Note: The MMMIDIHEADER data structure is defined in the MIDIOS2.H file.
