   MODULE  : mfw_ffs

   PURPOSE : This module contains FFS Interface functions.

   HISTORY:

    xrashmic 22 Aug, 2004 MMI-SPR-32798
    Adding the support for screen capture using a dynamically assigned key.

    Apr 14, 2005	REF: CRR 29991   xpradipg
    Description:	Optimisation 5: Remove the static allocation and use dynamic 
    			allocation/ deallocation for pb_list and black_list
    Solution:	The static definition is removed and replaced with the dynamic
    			allocation   

    Oct 19, 2004 REF: CRR MMI-SPR-26002 xkundadu 
    Issue description:  Golite booting problem.
    Solution: If the FFS is not formatted, prevent writing into FFS.

    Aug 25, 2004  REF: CRR 20655  xnkulkar
    Description: Voice Memo functionality not working
    Solution:	  The voice recording functionality was failing because 
    			 " mmi" folder is not present. As a solution, we create the 
    			 "mmi" folder and then proceed with recording.
