Enumeration Type Documentation

MemHeadFlag

enum MemHeadFlag

Enumerator
MEMHEAD_FLAG_FROM_CPP_NEW	This block of memory has been allocated from CPP new (e.g. #MEM_new, or some guardedalloc-overloaded new operator). It mainly checks that MEM_freeN is not directly called on it (#MEM_delete or some guardedalloc-overloaded delete operator should always be used instead).
