Existing file I/O APIs are modified to fail safely on OSS files larger than 2 GB. These
APIs return an error (EOVERFLOW or EFBIG) when an action cannot be performed on
OSS files larger than 2 GB or an attribute cannot be represented for such a file. The
large OSS file safe I/O APIs include:
•
creat()
•
open()
•
read()
•
write()
•
ftruncate()
