20.6.5 Creating the Header File

You must also create the SELECT.H header file for the Select library. This file contains the definitions for the constants used in the functions, as well as function definitions. The header file should look like this:

void FAR PASCAL StartSelection(HWND, POINT, LPRECT, int);
void FAR PASCAL UpdateSelection(HWND, POINT, LPRECT, int);
void FAR PASCAL EndSelection(POINT, LPRECT);
void FAR PASCAL ClearSelection(HWND, LPRECT, int);

You should also use the header file in applications that use the selection functions. This will ensure that proper parameter and return types are used with the functions.
