Hello all,
I have a file of binary data. I want to read this file and parse the data in
it. The format of the file is:
8 bits number of data pakets
6 bits offset
20 bits time
8 states
How can I read this fields in binary? I see the struct module and the
binascii, but I can't split the diferent fiels.

Hi!
Whats the canonical way for handling raw data. I want to read a file without
making any assumption about its structure and store portions of it in memory
and compare ranges with constant byte sequences. _I_ would read it
into arrays of unsigned char and use C's memcmp(), but as you see Im a
novice C++ programmer and think that theres some better, typically used,
way.
Regards

27.4.2.1.4 Type ios_base::openmode
Says this about the std::ios::binary openmode flag:
*binary*: perform input and output in binary mode (as opposed to text mode)
And that is basically _all_ it says about it. What the heck does the binary
flag mean?

Hello:
I am receiving a Binary File in a Request from a application. The
stream which comes to me has the boundary (Something like
"---------------------------39<WBR>0C0F3E0099" without the quotes),
and also
some more text like this and file name (e.g. "Content-Disposition:
form-data; name="upload_file"; filename="C:\testing\myfile.da<WBR>t"
Content-Type: application/octet-stream")

Has anyone written code that successfully manipulates binary file data
using Javascript?
It might---and in the case of doing I/O, will---make use of browser-
specific functions (ActiveX/COM with Internet Explorer, XPCOM/XPConnect
with Mozilla/Firefox).
I am writing client-side code that will generate binary data for producing
a GIF file through an OBJECT element. (The GIF is an image of a line and
points on a two-axis plot.)

I've read in a book:
<quote>
With a binary-mode stream, you can't detect the end-of-file by looking
for EOF, because a byte of data from a binary stream could have that
value, which would result in premature end of input. Instead, you can
use the library function feof(), which can be used for both binary- and
text-mode files:
int feof(FILE *fp);

Dear all, I'm new to the forum, I'm really sorry if this has appeared elsewhere. I'm not really a programmer and am having major difficulties handling a binary stream which I am trying to read and process in vb.net.
The stream is coming in from an FTDI chip and should contain 64 8-bit values.
An example of the stream is here

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
