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().
