Function Pointers in C Just as a variable can be declared to be a pointer to an int, a variable can also declared to be a pointer to a function (or procedure). For example, the following declares a variable v whose type is a pointer to a function that takes an int as a parameter ...
we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you should have the basic knowledge ofFunctionsandPointers in C.

If you really want to use function pointers in C++, you can still use the same C-style syntax shown above or the type aliases below. As a function pointer type alias: using typeName = returnType (*)(parameterTypes); (example code) As a function type alias: using typeName = returnType...
连起来就是:fp1 is a pointer to a function that takes an int and returns a pointer to an array of 10 void pointers. 是不是超简单?这个方法我其实是从Thinking in C++, Volume 1学到的,然后自己总结了下,并取了个沙雕但是个人认为有助于理解的名字,不懂为什么其他教程都没有这样教,再来一个: ...
I want to use "callback functions" in C/C++ DLL, so I want to set "function pointers" as arguments of C/C++ DLL adaptors in TestStand.Could you show me the way how TestStand C/C++ DLL adaptor work with such function pointers as arguments?
