move m_burn and function attributes to dbhelpers use m_burn for libtomcrypt zeromem() too 2016-03-17 15:21:33 +00:00			`#include "dbhelpers.h"`

Just use memset, it should'be be optimised out in a separate file --HG-- branch : fuzz 2017-05-25 14:19:46 +00:00			`volatile void *p = data;`
avoid volatile cast warning 2018-03-01 15:46:07 +00:00			`memset((void*)p, 0x0, len);`
