C++ allows you to pass a pointer to a function. To do so, simply declare the function parameter as a pointer type. Following a simple example where we pass an unsigned long pointer to a function and change the value inside the function which reflects back in the calling function − #inc...

In this tutorial, you will learn how to pass a pointer to a function as an argument. To understand this concept you must have a basic idea ofPointersandfunctions in C programming. Just like any other argument, pointers can also be passed to a function as an argument. Lets take an exampl...
The ultimate solution is to generalize the idea for any pointer type, providing a generic wrapper for pointers to be passed through C++ AMP. We need to provide an interface compatible with a pointer concept and carefully mark only functions not operating on pointers as C++ AMP restricted. The ...
First of all,char *board2[0]is an array of 20 pointers to char. Writingchar (*board)[20]instead yields a pointer to an array of 20 char. C's declarations are supposed to model the usage of the variable being declared. When subscripting an array, the brackets appear after the variable...
One would typically have a mexAtExit function registered as well to clean things up if the mex function is cleared. Also, why do you imply that C structures cannot have function pointers as part of the structure? They most certainly can. Or did I misunderstand you? 1 Comment gujax on...
I'm using function pointers and object-oriented programming techniques in my application. Most of the time my program works as expected. But when I try to pass several parameters to functions that are called via pointers, I get the following compiler error message: ...

Pointers and references are just another C++ type and when they are passed around you do so by value. Now, what about the case where we don't want to modify the value? There's no need to pass by reference or pointer, right? Wrong! Now, in the case of fundemental types it probably...
