Function Pointer C Typedef

Function Pointer C Typedef. Pointers Usage in C++ Beginners to Advanced CodeProject In C, a function pointer is a variable that stores the address of a function that can later be called through that function pointer The difficulty lies in the pointer to functions syntax and readability in C and C++, and the typedef can improve the readability of such declarations

Alternatively, we can define a new type alias of a function pointer using typedef to make code more readable It behaves similarly as we define the alias name for any command in a C program.

Simple Function Pointer Example In C

To use it we create a variable of the created type and. In the following code sample, we define a pointer to a void function without any arguments; nonetheless, both printInt and printDouble function addresses are stored in the variable of type FuncPtr. You want a type-id, which is essentially exactly the same as a declaration except you delete the declarator-id.The declarator-id is usually an identifier, and the name you are declaring in the equivilant declaration.
