Suppose I'm using stdio calls to write to a disk file.
One possible error condition is no space on file system
or even (in unix environment) a ulimit of 0 bytes.
Which calls would be expected to return error codes for
such conditions?
Would it happen on the writes (fwrite, fprintf, fputs ...),
or as they actually write to io buffers, might the errors
not occur until the data is flushed or the file is closed?

Does anyone know a standard (or supported on Linux, Mac, Win32) way to
clear a read stream buffer (standard ANSI C file stream)?
I would even settle for a platform specific way of doing it.
And no, I know I can use direct low level I/O or non-buffered to do
reads, but for my app, I need the buffering. I can implement myself,
but this is not optimal.
Example, I open a read only file using fopen(). I periodically know

Hi,
I am new to the c-programming language and at the moment I am
struggling with the following:
I want to read a file using fread() and then put it in to memory. I
want to use a (singel) linked list to continousely (dynamically) free
up more memory when needed and put the buffers with the data of the
file on a sort of stack.
The problem is that i have no idea how to do this.

Hi
Generally,
FileInfo fi = new FileInfo(path);
long size = fi.Length;
gets you the length of a file in bytes. However, when copying files, even
while the copy operation is still in progress, the filesize, as indicated in
Windows Explorer or derived with the above two lines of code, will be the
size of the file once the copy operation has completed. Is there a way to

I am trying to stream out a PDF file via the response object and when I
execute the code it always brings up the first document that I pulled
up.Even when I step through the code, I can see the new values in
theData string array (see code below), but it serves up the first
document that I had run this code with. I streamed theData into a text
file to look at the values and it contained the appropriate ones for
the new document. Even when I...

I have a 250 Gbyte file (occupies the whole hard drive space) and want
to change only eight bytes in this file at a given offset of appr. 200

How can I do that in Python?

How can I inherit from file but stil create an instance that writes to
stdout?
-----------
I'm writing a file-like object that has verbosity options (among
some other things). I know I could just set self.file to a file object
rather than inheriting from file. I started with something like this
(simplified for clarity):

Hi
I'm running an ASP.NET web application under IIS. I'm inserting a cache
object with a file based CacheDependency. I've noticed that when the file
changes the Cache object is not always immediately invalidated.
e.g. Cache.Insert("myobj", data, new CacheDependency(filePath));
When I make a change to the file 'filePath' and call the object from the
cache it is not null. I'm disposing of the FileStream object immediately

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
