In writing software that requires CSPRNGs, what is the prefered method (for you) in generating them (non-standard library as well as standard library)?

Solved.

packet is a pointer, so to access a member I need to use ->

I am going to have a data structure that stores a name, and associated with this name will be a list of codes.

How do you use fgets() to read from console input?

Hi there;

I want to repeatedly check for input using scanf if a given input is "invalid". I have made my code, but it seems if I enter a "wrong" value, it will loop and crash - spewing the...

I am making a simpel list code example for something, and I've got a bug I can't solve (should I be the one teaching here....? :confused:)

Anyway;

Writing the post was an inspiration in itself for me :)

Hi;

I want a way to remove leading and trailing whitespace from a string. I imagine i'm going to be making use of a loop and isspace(), but beyond this I cannot think how I can take in an array,...

Hi there;

I know what regular expressions are, and have used very simple ones before - but I don't know if they can be used in C, or how to use them. I do know, though, that regex would save me a...

Thanks everyone for your help - I went with this solution, and it works :)

Hi there;

I want to pass a pointer to an array to a function, so my second function can modify the array.

The problem I am coding for is a string - searching for commas and replacing them with...

Ok got it working :) Except for one problem now. The printlist() function prints a "0" at the first print.. but I can't see why:

Hi;

Thanks again for your help.

I now get the following warning, and still no printing:

Ok, got that fixed. Now my printlist function isn't printing anything...

Ok, here is my code again.

It falls over at;

/* DEBUG */ printf("tail set to temp.\n");
tail = temp;
with a seg fault.

And I am completely stumped as to why i am getting it.. for all intents and purposes, I cannot see a flaw (by eyeballing the code).

How do I ignore the whitespaces, say if they were deliminated by tabs instead?

I need a help with a problem I am trying to code around.

I need to take in a line - in the form "xxx $y, $y, $y". The line is always in this form. xxx can be any character, and the...

Hi there;

I want to know how to get a function to return a string in C. I know it cannot be done by simplying returning a character array, any ideas?
