Hello,
I have to read a file with a single "command" per line. But how do I read to
the end of the line?? I am using C style filepointers (not by choice :( )
Thanks for any help!

Greetings,
I need to read (unformatted text) from stdin up to EOF into a char
buffer; of course I cannot allocate my buffer until I know how much
text is available, and I do not know how much text is available until I
have read it... which seems to imply that multiple reads of the input
stream will be inevitable.
Now I can correctly find the number of characters available by:

- The value of the object allocated by the malloc function is used
(7.20.3.3).
- The value of any bytes in a new object allocated by the realloc
function beyond the size of the old object are used (7.20.3.4).
Something like this (include and checkings omitted):
p = malloc(sizeof(*p) * 5);
p = 1; p = 1; p = 1;

In this context would an indeterminate value lead
down the path to undefined behavior?
(void)foo->member;
I want to keep my interface consisent in my program
so I have this one function which is passed an argument
that it doesn't need.
So I can only think of using it this way as a viable method

hi
I have some trouble reading this macro:
#define SMC_inl(r) (*((volatile dword *)(SMC_BASE_ADDRESS+(r))))
also consider that SMC_BASE_ADDRESS is address base of I/O mapped
peripherial registers, r is register offset.
Does that read: return 32bits of data stored in memory location
SMC_BASE_ADDRESS+r.

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.

I am a newbie and going through "The C programming language" by
Kernighan & Richie on my own time (I'm not a programmer but I want to
learn because it can save me time in my normal job, and it is kind of
fun). As I go through the book, I seek to do all the exercises because
they are very useful, and good, but it seems like I am just stumbling
through somewhat. In particular, I don't really know how to think about
"catching errors", or how...

Hi,
I am having a problem that I have been trying to solve for the last 2 weeks. This might be seen in many travel sites like lastminute.com. The situation is simple. I need an indeterminate progress bar. I enter the search criteria/parameters (From/To Date & Destination) in page ‘A’. I click the search button now. I need to be transferred to Page ‘B’, which is empty but consists of a progress bar like image displaying any message and then I...

Hello,
Let’s assume the following piece of code :
This code works fine, its output is : "Exception : Could not execute f9".
Nevertheless, in the catch clause, the pointer c is indeterminate, the pointee may have been lost.

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,...
