Hello
I've read here that only C language has a standard 64bit integer.
Can you please tell me what are the reasons for this ? What is special about
C language ?
Can you please show me some references to this integer type ? When was it
introduced ?
Thank you

Following a discussion on another thread here... I have tried to understand
what is actually standardized in C++ regarding the representing of integers
(signed and unsigned) and their conversions. The reference should be 3.9.1
(Fundamental types), and 4.7 (Integral conversions).
It seems to me that the Standard doesn't specify:
1) The "value representation" of any of these types, except that (3.9.1/3)
"... The range of nonnegative...

Hey,
I was wondering if it was possible to determine if you hit 'EOF' using
fseek? I'm using fseek to traverse through the file from start to end
and capturing the data into a linked list structure. However, my loop
doesn't seem to work well - it totally fumbles out actually:
while ((a = fseek(fp,0,SEEK_CUR)) == 0){
// code here
}

Hi All,
I hope this is the correct mailing list for this question. But neither
postgresql.org nor google could help me out on this subject.
I did find one disturbing topic on the mailing list archives
(http://archives.postgresql.org/pgsql-admin/2000-05/msg00032.php), but
since it was quite old I'm posting my question anyway.
I'm writing a generic database layer that should support a fixed number
of generic numeric types on a number of...

Hi all,
Can the compiler chose the type of an enum to be signed or unsigned
int? I thought it must be int; looks like it changes based on the
assigned values. Below if I don't initialize FOO_STORE to be, say -10,
I get a warning about unsigned comparison and I'm seeing an infinite
loop.
If I do initialize FOO_STORE = -10, I don't see any warnings. No
infinite loop.

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'm a network technician in training and I need your help.
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...
