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