void * RTFindPhysMem(const void * Physical, unsigned Bytes, int MinAccess);

Parameters

Physical

The address of the physical memory to find.

Bytes

Specifies its size in bytes.

MinAccess

Specifies the minimum access level required. Values RT_PG_NOACCESS, RT_PG_SYSREAD, RT_PG_SYSREADWRITE, RT_PG_USERREAD, and RT_PG_USERREADWRITE are supported.
