mallocis the core function for dynamic memory allocation in C that takes a single integer argument representing the number of bytes to be allocated. To allocate the memory of the customstructobject that has been defined, we should call thesizeofoperator and retrieve the amount of memory the obj...
In this example, we first allocate memory for the students array dynamically using malloc. This allows us to create an array whose size can be determined at runtime. We then initialize each struct individually. Finally, we free the allocated memory to prevent memory leaks. This method is parti...
Understanding malloc() Why Use malloc()? How to Use malloc() Best Practices Common Mistakes Advanced Usage Conclusion In the realm of C programming, efficiently managing memory is crucial for building high-performance applications. One of the tools at a programmer’s disposal for such a task is...
That's not actually an answer to the question. Read the arguments to VirtualAlloc() in the question again: the two allocations use two different ranges of pages. I'm having a similar problem, where code that walks the virtual space calling VirtualAlloc() with specific base addresses fails to...

I was using a lot of OutputDebugString() API in legacy code using Visual C++ 6.0 to 2015 on OS from W95 to W10.Right now, it seems that OutputDebugString() is not working anymore in recent builds of VS2017.On W7 and later, I had to make some tricks with registry (adding a ...

Raw tcp sockets in C Raw sockets can be used to construct a packet manually inside an application. In normal sockets when any data is send over the network, the kernel of the operating system adds some headers to it like IP header and TCP header. So an application only needs to take ca...
m: a variable (or other lvalue) that is set to the maximum value found x: an array where the search is performed n: the number of elements in the array Note that after argument substitution, the expressions which are specified as macro parameters are evaluated only once. That is achieved...
