Thanks. I had to do data = realloc(data, ++datalen * sizeof(char)). I forgot the "data = ". I just looked it up in my little c reference book.

void* realloc(void* p, size_t size);

Hi, I'm making a little program that will send email. I am fine with the sockets, but I keep getting a segmentation fault and I don't know why:$. I'm trying to make a loop that will let the user...

I figured it out after about a bit of searching. For anyone having this same problem: apparently, Cygwin can't use IPv6 by default. I went to http://win6.jp/Cygwin/ and downloaded the files I needed...

Hi, I installed cygwin recently and wanted to do some network programming with it. Since I have never used unix sockets before, I'm reading Beej's Guide To Network Programming. I took this from...

Hi, I'm using GNU MP to get very precise square roots of numbers. I have three questions about my code below.

Hi, how would I get the temperature and percentage of load for my CPU, GPU, and other things like the hard drive? I'm on Windows XP. Is there something in the Win32 API or what?

Hi, I was wondering if there was an alternative to the ShellExecute function of the Windows API; one that is universal on every OS. Is there one?

I switched from Dev-C++ to Code::Blocks recently. The interface is awesome. I'm using the MinGW compiler, so there's no difference in compile time (they are using the same compiler). The only thing...

Bubble sorts are very easy to make. Just Google "bubble sort algorithm".

This is a very complex sort. There's pseudocode on Wikipedia http://en.wikipedia.org/wiki/Heap_sort.

Hi, how would I make a simple kernel in C that I could boot on my PC?

Thanks! That works perfectly! :)

In Dev-C++ 4.9.9.2:
`bool' undeclared (first use in this function)

(Each undeclared identifier is reported only once for each function it appears in.)

Hi, I keep getting an undefined identifier error when I try to do this:


typedef char bool; // Make a bool type
char false = 0, true = 1; // Make true and false

void foo()
