Data Type : Standard

LNCALLBACKPTR - Pointer to a callback routine.

#include <global.h>

Definition :

#if !defined(OS2)

   #define LNCALLBACKPTR LNCALLBACK FAR *

#else

   /* OS/2 requires a separate macro because the ordering of function
      modifiers for function pointers is different.  This prevents us
      from inserting _System in a uniform place (e.g. a replacement
      for PASCAL). */

   #define LNCALLBACKPTR * _System

#endif

Description :

Pointer to a callback routine.

Sample Usage :

Callback pointer declaration from nsfsearc.h:

typedef STATUS (LNCALLBACKPTR NSFSEARCHPROC) (
   void          far * EnumRoutineParameter,
   SEARCH_MATCH  far * SearchMatch,
   ITEM_TABLE    far * SummaryBuffer);
