You need to send the file size before sending actual file. Because this is binary data, you MUST NOT treat this as string data.
Also while reading/writing you should check how bytes has been actually read/written. Based on this you should move your read/write point. e.g. while writing it should be
Due to the massive Upload speeds killing .... or overstressing our schools network...... my school has blocked port 6969 (the most common BitTorrent port). So I cant connect to the tracker anymore, in other words no more downloading from school :(

Hi,
I'm behind a university firewall where nearly all ports are blocked. Therefore I've set up a ssh tunnel to my comp at home so that I can bypass the uni firewall and use bittorrent. I used mainly these 3 guides to setup the tunnel: http://freebsdcluster.org/~lasse/sshazureustunnel/ , Whalesalad... (1 Reply)

I wrote a simple program that generates a random word 10,000,000 times.
I wrote it in python, then in C++ and compared the two completion times. The python script was faster! Is that normal? Why would the python script be faster? I was under the impression that C++ was faster. What are some of... (2 Replies)
Long story short: I'm working inside of a Unix SSH under a bash shell. I have to code a C program that generates a random number. Then I have to call the compiled C program with a Perl program to run the C program 20 times and put all the generated random #s into a text file, then print that text... (1 Reply)

Hi all,
Earlier today, I read an article on how to detect BitTorrent traffic using tshark (the cli version of Wireshark).
I wanted to have a go at creating a simple script, that when BitTorrent packets are detected the network connection will be throttled. The thing is that I am not great at... (1 Reply)

tiffrewritedirectory
TIFFWriteDirectory(3T)TIFFWriteDirectory(3T)NAME
TIFFWriteDirectory, TIFFRewriteDirectory - write the current directory in an open TIFF file
SYNOPSIS
#include <tiffio.h>
int TIFFWriteDirectory(TIFF* tif)
int TIFFRewriteDirectory(TIFF* tif)
DESCRIPTION
TIFFWriteDirectory will write the contents of the current directory to the file and setup to create a new subfile in the same file. Appli-
cations only need to call TIFFWriteDirectory when writing multiple subfiles to a single TIFF file. TIFFWriteDirectory is automatically
called by TIFFClose and TIFFFlush to write a modified directory if the file is open for writing.
The TIFFRewriteDirectory function operates similarly to TIFFWriteDirectory but can be called with directories previously read or written
that already have an established location in the file. It will rewrite the directory, but instead of place it at it's old location (as
TIFFWriteDirectory would) it will place them at the end of the file, correcting the pointer from the preceeding directory or file header to
point to it's new location. This is particularly important in cases where the size of the directory and pointed to data has grown, so it
won't fit in the space available at the old location.
RETURN VALUES
1 is returned when the contents are successfully written to the file. Otherwise, 0 is returned if an error was encountered when writing
the directory contents.
DIAGNOSTICS
All error messages are directed to the TIFFError(3T) routine.
Error post-encoding before directory write. Before writing the contents of the current directory, any pending data are flushed. This mes-
sage indicates that an error occurred while doing this.
Error flushing data before directory write. Before writing the contents of the current directory, any pending data are flushed. This mes-
sage indicates that an error occurred while doing this.
Cannot write directory, out of space. There was not enough space to allocate a temporary area for the directory that was to be written.
Error writing directory count. A write error occurred when writing the count of fields in the directory.
Error writing directory contents. A write error occurred when writing the directory fields.
Error writing directory link. A write error occurred when writing the link to the next directory.
Error writing data for field "%s". A write error occurred when writing indirect data for the specified field.
Error writing TIFF header. A write error occurred when re-writing header at the front of the file.
Error fetching directory count. A read error occurred when fetching the directory count field for a previous directory. This can occur
when setting up a link to the directory that is being written.
Error fetching directory link. A read error occurred when fetching the directory link field for a previous directory. This can occur when
setting up a link to the directory that is being written.
