Hi,
Is there a way in C++ ( using the iostream.h ) or in C ( using the
stdio.h and the like ) to control precisely how
data gets saved to a file. What I mean by this is, can I control exactly
at which offset within the file my data blocks will go.
I need that, because I wrote a client that receives a file from a server.
In my implementation I am using UDP, so there is no guarantee about the
order in which the packets that constitute that file arrive. Every packet
though is numbered and its size (except for the last packet) is known.
That lets me calculate exactly its starting and ending offset position
with in the file.
It would be pretty neat if I could save the file to my disk, right away
as its packets keep on coming, based on the above calculation. I am sure
that is possible; unfortunately I don't know how to do it.
I did some experimentation with fseek, but all I got was segmentation
faults. :(
Any help would be appreciated,
mich
