* These routines are used for reading from and writing to disk files |
| 42 |
* or devices in sony.cpp, disk.cpp and cdrom.cpp. Their purpose is to |
| 43 |
* hide all OS-specific details of file and device access. The routines |
| 44 |
* must also hide all restrictions on the location or alignment of the |
| 45 |
* data buffer or on the transfer length that may be imposed by the |
| 46 |
* underlying OS. |
| 47 |
* A file/device is identified by a "filename" (character string) that |
| 48 |
* may (but need not) map to a valid file path. After Sys_open(), the |
| 49 |
* file/device is identified by an abstract "file handle" (void *), |
| 50 |
* that is freed by Sys_close(). |
