Using v1.1. of the framework:
I was writing a wrapper around the java.util.zip.ZipOutputStream class so
that my app could access it using standard FileStream semantics and I ran
into a conversion problem. The signature for the write method is void
ZipOutputStream.Write(sbyte array,int off,int len) so I figured a simple
conversion from byte to sbyte would do the trick.
Now, my understanding of an sbyte is that it is a signed byte that...

I give up, how do I make this not fail under 2.4?
fcntl.ioctl(self.dev.fileno(),0xc0047a80,struct.pack("HBB",0x1c,0x00,0x00))
I get an OverflowError: long int too large to convert to int
ioctl() is expecting a 32-bit integer value, and 0xc0047a80 has
the high-order bit set. I'm assuming Python thinks it's a
signed value. How do I tell Python that 0xc0047a80 is an
unsigned 32-bit value?

Hi!
I need to convert from a unsigned char array to a float. I don't think
i get the right results in the program below.
unsigned char array1 = { 0xde, 0xc2, 0x44, 0x23}; //I'm not sure in
what order the data is stored so i try both ways.
unsigned char array2 = { 0x23, 0x44, 0xc2, 0xde};
float *pfloat1, *pfloat2;

Hi,
I need to convert a Binary value to Decimal. I've been told that the
value is an unsigned one. How can I do this?
I use memcpy into an unsigned char variable, but when I print the
value I got a negative value.
For example if I'm using the xd -c (Unix) on the file, I can see the
value FFFFFFFFFFFFFFA2 which using the memcpy as described above I get
-94.
But the real value that I'd expect to get is a positive one.

I have a general idea about how negative number systems work, but I'd
appreciate some clarification if anyone would be willing to help me.
Let's assume we're working with an 8-Bit signed integer, and that it
contains no padding.
Firstly, I realise that the MSB is known as the sign-bit, and that it
indicates whether the number is positive or negative (irrespective of
which negative number system is used).

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
