no matter how many bits are the offset type defined, you still can
access file again and again.
llseek will put file pointer in the offset position. Then you can call
llseek again and again.
Till the file pointer is in the position what you want.

Hi all
llseek method has its second argument as offset which is of type unsigned long.
And the last argument decides whence i.e from where to start the offset, right?
Now i have a doubt.
If the data type of offset is unsigned long this means i can only
access a file till its 2^32 byte after if i start from its beginning,
using llseek.
On the other hand ulimit -a shows me i can have a file size of
unlimited size, which is indeed some value subjected to storage space
on which file resides and also the filesystem.right?
Then does this means i cant access a file beyond its 2^32 byte using
llseek and starting from its beginning?
Is it so or am i missing something here?
Any pointers or links will be appreciated.
Thank you.
