   DWORD                 seg,  
   DWORD                 offset,  
   DWORD                 length,  
   IDiaEnumLineNumbers** ppResult  
);  

Parameters

seg
[in] Specifies the section component of the specific address.

offset
[in] Specifies the offset component of the specific address.

length
[in] Specifies the number of bytes of address range to cover with this query.
