Describes an entry in an address map.

Syntax

struct DiaAddressMapEntry {   
   DWORD rva,  
   DWORD rvaTo  
};

Elements

rva
A relative virtual address (RVA) in image A.

rvaTo
The relative virtual address rva is mapped to in image B.

Remarks

An address map provides a translation from one image layout (A) to another (B). An array of DiaAddressMapEntry structures sorted by rva defines an address map.

To translate an address, addrA, in image A to an address, addrB, in image B, perform the following steps:

  1. Search the map for the entry, e, with the largest rva less than or equal to addrA.

  2. Set delta = addrA – e.rva.

  3. Set addrB = e.rvaTo + delta.

    An array of DiaAddressMapEntry structures is passed to the IDiaAddressMap::set_addressMap method.
