If this causes the current file offset to exceed the current file length, the current file length in the I node table entry is set to the current file offset (that is, the file is extended). If you open a file with the O_append flag, the corresponding flag is also set to the file status flag of the file table entry. Each time a write is performed on this file with an append write flag, the current file offset in the file table entry is first set to the length of the
