- *
- * File: 
- * eas_hostmm.c
- *
- * Contents and purpose:
- * This file contains the host wrapper functions for stdio, stdlib, etc.
- * This is a sample version that maps the requested files to an
- * allocated memory block and uses in-memory pointers to replace
- * file system calls. The file locator (EAS_FILE_LOCATOR) handle passed
- * HWOpenFile is the same one that is passed to EAS_OpenFile. If your
- * system stores data in fixed locations (such as flash) instead of
- * using a file system, you can use the locator handle to point to
- * your memory. You will need a way of knowing the length of the
- * data stored at that location in order to respond correctly in the
- * HW_FileLength function.
- * 
- * Modify this file to suit the needs of your particular system.
- *
- * EAS_MAX_FILE_HANDLES sets the maximum number of MIDI streams within
- * a MIDI type 1 file that can be played. 
- *
- * EAS_HW_FILE is a structure to support the file I/O functions. It
- * comprises the base memory pointer, the file read pointer, and
- * the dup flag, which when sets, indicates that the file handle has
- * been duplicated. If your system uses in-memory resources, you
- * can eliminate the duplicate handle logic, and simply copy the 
- * base memory pointer and file read pointer to the duplicate handle.
