what is the difference?
if I open a text file in binary (rb) mode, it doesn't matter... the read()
output is the same.

Hi!
maybe someone can help me?!
I want to use fstream to read an .au file . This .au file includes
multiple information in its header. a MagicNumber, the No of Channels
used, and so on.
In hex code the data is 2e736e64 (the magic number). But when i read
the number with fstream i get 646e732e. Why are the numbers messed up
in order?!
I am using g++ 2.95.

I'm trying to replace some bytes in a file using fstream but all I seem to
be able to do is append or 0 the file then write... Basicaly I just need to
replace the first 512 bytes of the file with some buffer(but eventually I
will need to replace random blocks in the file at different locations). Is
there anyway to do this efficiently using fstream? (I know I can duplicate
the file, but it seems a waste to rewrite the same data for no...

Hi,
I'm trying to open a file (any file) in binary mode and save it inside
a new text file.
After that I want to read the source from the text file and save it
back to the disk with its original form. The problem is tha the binary
source that I extract from the text file seems to be diferent from the
source I saved. Here is my code:
1)
handle=file('image.gif','rb')

Is it possible at all to read a binary file larger than 2GB on a 32-
bit system? I tried the following:
#include <iostream>
#include <fstream>
using namespace std;
int main(int argc, char *argv) {
fstream fsBin;
fsBin.open(argv, fstream::in | fstream::binary);

I have a program which opens a fstream in binary input+output mode, creating
the file if it doesn't exists. But writing doesn't works after reading, it
must be something obvious that I am not aware of.
f.open(filename,ios::in | ios::out | ios::binary | ios::trunc)
The program flow is
1) write some data
2) read the data

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
