This function creates a captioning window and returns the handle of that window to the application. This caption window is a child of hwndParent, and does not become visible until the Caption DLL is sent a CC_START command.
An application calls this function once, during its initialization (or before it wants to use the caption services).
#include <os2.h> HWND hwndParent; ULONG rc; rc = ccInitialize(hwndParent);
