template<typename T >
bool forbidPage (const T *addr)
 forbid access to the page containing addr, setting its prot to PROT_NONE
bool forbidPage (const void *addr, size_t objSize)
 forbid access to the page containing addr, setting its prot to PROT_NONE
bool forbidPage (const void *addr)
 FIXME this will not work well for objects spanning across pages.
bool protectPage (const void *addr, size_t objSize, int prot)
 void* version of protectPage. Used to implement all others

 was the page containing address accessed?

Member Function Documentation

template<typename T >
bool PageAccessControl::protectPage ( T addr,
int  prot 
) [inline]

protect the page containing addr, record the amount of memory we protected NOTE To avoid SEGV, if PROT_WRITE is requested the remainder of the page containing the object at addr will be leaked with malloc before being write-locked
