I am just wanting to know how offsetInFile works? and what is the difference between seekToFileOffSet. and code examples you know of would be helpfull as well:)
For standard file descriptors, -[NSFileHandle offsetInFile]
and -seekToFileOffset:
have straightforward POSIX equivalents:
[handle offsetInFile];
=> off_t offset = lseek([handle fileDescriptor], 0, SEEK_CUR);
[handle seekToFileOffset:off];
=> off_t offset = lseek([handle fileDescriptor], off, SEEK_SET);
The difference between them is that the first returns the current offset, while the second changes the offset.
