The block manager is responsible for creating and initialising the structures and tables to allow access to the strings, icons sounds and vibrations required by the MMI. Each of these items is effectively a contiguous block of memory, which is accessed via a block resource. Each of the block resources are provided by this package ******************************************************************************** $History: MmiBlkManager.c 25/10/00 Original Condat(UK) BMI version. $End *******************************************************************************/ /******************************************************************************* Include Files *******************************************************************************/ #define ENTITY_MFW /* includes */ #include <string.h> #include <stdio.h> #include <stdlib.h> #if defined (NEW_FRAME) #include "typedefs.h" #include "vsi.h" #include "pei.h" #include "custom.h" #include "gsm.h" #else #include "STDDEFS.H" #include "custom.h" #include "gsm.h" #include "vsi.h" #endif // #include <malloc.h> #include "MmiBlkManager.h" /******************************************************************************* Local structures and definitions *******************************************************************************/ /* Define a type for the manager control block, this contains an array identifying each of the resource manager handles which are populated as part of the initialisation sequence */ #define BLOCK_MANAGER_KEY 0x00BABE01L #define BLOCK_MANAGER_ENTRY_COUNT 0x00000010L typedef struct _tManagerEntry_ { tBlkId Id;
