I don't think that'll work. O_LARGEFILE is typically used as a flag |
| 35 |
within fopen(), eg: |
| 36 |
|
| 37 |
fd = fopen("movie.mpg", O_RDONLY|O_LARGEFILE); |
| 38 |
|
| 39 |
There is the very real possibility that the program doesn't have the |
| 40 |
capability to read large files. In which case, a patch is in order. |
