Question

INTERNETAPIHINTERNETWINAPIInternetOpenW(IN LPCWSTR lpszAgent,IN DWORD dwAccessType,IN LPCWSTR lpszProxy OPTIONAL,IN LPCWSTR lpszProxyBypass OPTIONAL,IN DWORD dwFlags);

Answer 1

typedef
INTERNETAPI
HINTERNET(*
WINAPI
funcPtr_InternetOpenW)(
IN LPCWSTR lpszAgent,
IN DWORD dwAccessType,
IN LPCWSTR lpszProxy OPTIONAL,
IN LPCWSTR lpszProxyBypass OPTIONAL,
IN DWORD dwFlags
);
typedef
INTERNETAPI

WINAPI
HINTERNET(*funcPtr_InternetOpenW)(
IN LPCWSTR lpszAgent,
IN DWORD dwAccessType,
IN LPCWSTR lpszProxy OPTIONAL,
IN LPCWSTR lpszProxyBypass OPTIONAL,
IN DWORD dwFlags
);
funcPtr_InternetOpenW pFunc =InternetOpenW;

Answer 2

函数返回类型 (*函数名)();
这个函数指针的格式
