Type Definition Description WinAPI uses the FAR Pascal location in the API declaration, if you are writing a DLL with exporting API people, you can use this type of Callback in your own API to use in the application recursive routine, such as windows and conversations The position LPCSTR of the FAR PASCAL in the frame is the same as LPSTR, just LPCSTR is used for read-only string pointers, which defines similar (const char far *) uint-free integer type, whose size is determined by host environment (for Windows NT and Windows 9x are 32 bits); it is the synonym of unsigned int LRESULT window program Return Value LPARAM declares that the type used by LPARAM, LPARAM is the fourth parameter of the window, WPARAM is used, WPARAM is a window. The third parameter of the program LPVOID general pointer type, with (void *), can be used instead of LPSTR
