Example
This example shows a function that obtains all line numbers contained in a function using the function's address and length.
IDiaEnumLineNumbers* GetLineNumbersByAddr(IDiaSymbol *pFunc,
IDiaSession *pSession)
{
IDiaEnumLineNumbers* pEnum = NULL;
DWORD seg;
DWORD offset;
ULONGLONG length;
if (pFunc->get_addressSection ( &seg ) == S_OK &&
pFunc->get_addressOffset ( &offset ) == S_OK)
{
pFunc->get_length ( &length );
pSession->findLinesByAddr( seg, offset, static_cast<DWORD>( length ), &pEnum );
}
return(pEnum);
