DdfInitialize - Syntax

This function initializes the IPF internal structures for dynamic data formatting and returns a DDF handle. The application uses this handle to refer to a particular DDF panel.

#define INCL_DDF
#include <os2.h>

HWND     hwndHelpInstance;  /*  Handle of a help instance. */
ULONG    cbBuffer;          /*  Initial length of internal buffer. */
ULONG    ulIncrement;       /*  Amount by which to increment the buffer size, if necessary. */
HDDF     hddf;              /*  Handle to DDF. */

hddf = DdfInitialize(hwndHelpInstance, cbBuffer,
         ulIncrement);
