Your array traversal logic would be correct if M were an int **. However, since M is an int *, your row "pointer" must increment by c elements each time, assuming row major ordering.

Thanks for the help. Also thanks for pointing out that I need a pointer to a pointer if I allocate the data.

Also keep in mind that only one dimension can be unspecified, so foo[ ][ ] is invalid.

This is for the return value. The options I see are returning a pointer to the new data or passing a destination pointer to the function and assigning the data there (see original post.)

What if I am using larger structures, say 5 MB images? I clearly do not want to return that on the stack. Is there a preferred way to return the new data in that case?

Thanks for the help. Part of my question was determining a best practice. I was assuming I could not return a structure from a function. As far as asking about structures with pointers in them, I...

I will be modifying the contents of the structure. With the first function, I would create the structure and do a shallow copy, which I guess is a rather silly method. I suppose it would get much...

For a program I am working on, I need to perform some operations on vectors, such as vector addition. However, I am unsure of how best to write the functions to perform the operation. My vector is...

I should have clarified rolling a d6 until I don't get a 6. I mean that if I roll a 6 on that die, I keep the 6, roll again and add it to the running total, and if my new roll was a 6, lather,...

My reasoning behind using a linked list was to make the Basic_Die able to have multiple internal variables without affecting the outside view of the struct. This way, I could use more or less...

Unfortunately, I am programming in C, but using a lookup table is a method I forgot. However, I might be using many different sizes of dice. Further, in Storyteller, usually you score for rolls...

This is proper behavior. I suspect the reason for the difference is that the array size of mins is known at compile time. What happens if you specify



int sum(int ar[5], int n)


and take...

For some games I eventually want to program/play in, I want to create a framework that will roll dice in a number of different ways. For my test, I want a polyhedral dice structure, chosen as six...

Do you already have the inventory? If not, a linked list would be one way to store the data, and it is easy to traverse.

line2[j]


is not a pointer; the subscript dereferences the pointer. To get a pointer, you can use


&line2[j]

or

Also keep in mind that you may need to set up access to the port, as I/O access is often limited in userspace. If you are operating in kernel space or its equivalent, this shouldn't be a problem.

That makes sense. Thanks.

Thanks. I knew Python had something similar for serial ports, but I had forgotten about select's timeout.

Thanks. It's nice to know that my microcontroller work is applicable to a computer system.

I was looking up sig_atomic_t, and it appears to be typedefed int, with its typedef being performed...

I have some aspirations of one day programming a MUD engine, and I will need to be able to handle both user I/O and timed events. I have written a little program that uses SIGALRM to update the...
