Usestd::shared_ptrfor Multiple Pointers to Refer to the Same Object in C++ Since the manual management of dynamic memory happens to be quite hard for real-world projects and often is the main cause of the bugs, C++ provides the concept of smart pointers as a separate library. Smart pointer...
The solution to the above problem is Smart Pointers. Smart pointers automatically handle many of these problems. They are basically an object which behave like pointers i.e. wrap a bare pointer but provides extra functionality. So we should use these in place of bare pointers. Now, let us u...
Always remember to correctly initialize pointers. A mutex or a semaphore can be used to protect shared resources from concurrent access in multithreading. We should use the free() function Example 1: Program of Segmentation Fault by Dereferencing Pointer from Memory Block in C We have an illustrat...
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...
10. Don’t use spaces around the operators ., ->. If necessary, the operator can be wrapped to the next line. In this case, the offset in front of it is increased. 11. Do not use a space to separate unary operators (--, ++, *, &, ...) from the argument....
As a bit of an explanation why. References are secretly pointers under the surface. This means that what you are attempting to pass in to Read is a pointer to a 2 byte variable. Since Read expects a pointer to a 4 byte variable, then Read is able to write to 4 bytes, the lac...
Example (How to Create a Shared Library) Lets take a simple practical example to see how we can create and use shared libraries. The following is the piece of code (shared.c) that we want to put in a shared library : #include "shared.h" ...
Use smart pointers or other RAII-type wrappers to manage all resources. Avoid resource management functionality in your class destructor, because the destructor will not be invoked if the constructor throws an exception. However, if the class is a dedicated resource manager that controls just one ...
