can you define function pointer return integer pointer? answer is yes. and it should be like this---->
integer*(*function)();
and my question is , can you define function pointer return function pointer? if answer is no! teach me please. if answer is yes, tell me how please.
Of course you can. The easiest and most readible way is to have an intermediate typedef, something like this:
typedef int* (*pFunc)(void);
and then it's simply:
typedef pFunc (*pFuncRetFunc)(void);
typedef int* (*pFunc_t)(void);.
std::function as your return type... and be C++ style.
std::function has extra overhead compared to a simple function pointer. C++ style is to avoid paying for what you don't need.typedef int * (* (* FP)(void))(void);
This defines FP to be a type that represents a function pointer to a function returning a function pointer to a function returning a pointer to int. All function (types) involved take no arguments.
