Hope someone can help.
I am trying to read data from a file binary file and then unpack the
data into python variables. Some of the data is store like this;
xbuffer: '\x00\x00\xb9\x02\x13EXCLUDE_CREDIT_CARD'
# the above was printed using repr(xbuffer).
# Note that int(0x13) = 19 which is exactly the length of the visible
text

Hi All,
I am pretty new to python and am having a problem
intepreting binary data using struct.unpack.
I am reading a file containing binary packed data
using open with "rb". All the values are coming through
fine when using (integer1,) = struct.unpack('l', line)
except when line contains "carriage-return" "linefeed"
which are valid binary packed values. Error = unpack
string size dows not match format. It seems that

All,
I've got a process that creates some children and want to be alerted
when they die. To do this, the SIGCHLD signal is registered in the
process using sigaction to jump to a subprogram as soon as it's
received.
The problem comes when many children exit at the same time and their
father seems to miss some of them. This happens quite often, but not
always.

Hi there,
We have a compiler specific issue which requires us to force template instantiation. This works fine. The problem comes
when I try using std:find() on vector. Since vector has no member function find() and I have to use std::find(). The
linker fails on unsatisified symbols in find().
I think this is because find() is a template function and I have to force instantiation. However, I donot know the
correct syntax of doing so....

Hi!
I have a really long binary file that I want to read.
The way I am doing it now is:
for i in xrange(N): # N is about 10,000,000
time = struct.unpack('=HHHH', infile.read(8))
# do something
tdc = struct.unpack('=LiLiLiLi',self.lmf.read(32))
# do something

If I run:
testValue = '\x02\x00'
junk = struct.unpack('h', testValue)
Everything works but If I run
testValue = raw_input("Enter Binary Code..:") inputting at the
console '\x02\x00'
junk = struct.unpack('h', testValue)

Hi,
I am writing a small program to decode MS bitmap image. When I use statements as follow, it works fine:

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
