33     * These routines are used for reading from and writing to disk files
34     * or devices in sony.cpp, disk.cpp and cdrom.cpp. Their purpose is to
35     * hide all OS-specific details of file and device access. The routines
36     * must also hide all restrictions on the location or alignment of the
37     * data buffer or on the transfer length that may be imposed by the
38     * underlying OS.
39     * A file/device is identified by a "filename" (character string) that
40     * may (but need not) map to a valid file path. After Sys_open(), the
41     * file/device is identified by an abstract "file handle" (void *),
42     * that is freed by Sys_close().
