LIB_API Status mahaf_Init

(

)

LIB_API bool mahaf_IsPhysicalMappingDangerous

(

)

Returns

whether mapping physical memory is known to be dangerous on this platform.

callable before or after mahaf_Init.

note: mahaf_MapPhysicalMemory will complain if it is called despite this function having returned true.
