Comment(by anonymous):

 GENERIC_ALL maps to Full Control in windows... Whereas GENERIC_READ and
 GENERIC_WRITE map to your standard Read and Write permissions. Full
 control adds extra permissions for execute, plus things like Take
 Ownership and Change Permissions.

 I cant imagine why you would need GENERIC_ALL in the case for opening the
 mapped file for writing.  So I agree with the original poster that the
 reference to GENERIC_ALL should be GENERIC_READ | GENERIC_WRITE instead.
