I am running a C++ process on Solaris that needs
to find out how much diskspace is free and used on
the system.
Is 'system' in stdlib.h the only way to make OS calls
from C++?
In this case, I will probably be making unix calls like
'df' or 'statvfs' to get the diskspace information and
redirecting it to a file, and then opening and reading

I am currently learning C++ and am into a project for the end of the
semester finals. Everything is rosy except for one feature that I want
to include and can't find in my very large and expensive C++ books. Plus,
I don't want to ask the instructor because that will give my project away.
How do you call an external non C++ program, or possibly a system
function? For instance, I have some very good Perl modules from my last
class that...

If the C programs have UNIX system calls such as fork(), alarm(),
etc.., we should call it UNIX programs, not traditional C programs?
We couldn't compile the programs with system calls using VC++ compiler.
I need to compile it under UNIX platform. correct? any other
alternatives??
Please advise. Thanks!!

Whatis the proper way to handle errors from function calls?
For example, i normally have a main function, with calls to mine
or c functions. Should i check for errors in the functions called
themselves, or should i return a code to main and handle the error
there?
If i don't return them to main, except for the structure, what
use is the main function except for calling functions?

I inherited a C++ DLL that I need to remotely call multiple times
asynchronously. What I have developed is:
CSharp web application that makes asynchronous calls to a CSharp Web
Service. The Web Service calls the DLL, which does some heavy
processing, then sends the results back to the CSharp web application.
The problem is that the calls to the DLL in the Web Service are blocking
each other. If I send 10 async requests to the Web...

Hi, I keep resorting to com interop calls, for example I needed the
location of the carot in a text box and I had to use a win32API call
(GetCarotPos??) to do that.
It's one example, I could give several more that have come up over the
last few months, and it has raised a couple of questions the answers to
which could plug a few holes in my knowledge.
First, I'm uncomfortable using API calls purely because I don't fully
understand the...

I'm trying to write a thread-safe async method to send a message of the form

Hi,
I'm having difficulty finding any previous discussion on this -- I
keep finding people either having problems calling os.exec(lepev), or
with using python's exec statement. Neither of which I mean 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:

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...
