| Issue |
In QNX4, if we write to a file until the size exceeds 2GB, the write call returns zero bytes written but the file system becomes corrupted. Is this a known problem?
|
| Solution |
The 2 gigabytes is a POSIX implied limit: long (32 bits). This limitation is defined in the header /usr/include/sys/fsys.h.
If you need to write files this large, you may want to consider writing to a raw/empty partition. |
