FARPROC

FARPROC is a data type defined in the Windows API that represents a pointer to a function. The name stands for "Far Pointer to Function". This type is commonly used when dealing with functions that reside in different memory segments or when making calls to functions loaded dynamically from DLLs. It is essentially a generic pointer that can be cast to the specific function signature of the target function. When you obtain a FARPROC, you are receiving the memory address of a function, and you must cast it to the correct function pointer type before you can call it. This ensures type safety and proper function invocation. The use of FARPROC is prevalent in the Win32 API, particularly with functions like GetProcAddress, which retrieves the address of an exported function from a DLL. Understanding FARPROC is crucial for developers working with dynamic library loading and low-level Windows programming.
