IDiaSession::findLinesByRVA
Retrieves the lines in a specified compiland that contain a specified relative virtual address (RVA).
HRESULT findLinesByRVA (
DWORD rva,
DWORD length,
IDiaEnumLineNumbers** ppResult
);
Parameters
rva
[in] Specifies the address as an RVA.length
[in] Specifies the number of bytes of address range to cover with this query.ppResult
[out] Returns an IDiaEnumLineNumbers object that contains a list of all the line numbers that cover the specified address range.
Return Value
If successful, returns S_OK; otherwise, returns an error code.
Example
This example shows a function that obtains all line numbers contained in the specified function using the function's relative virtual address and length.
IDiaEnumLineNumbers* GetLineNumbersByRVA(IDiaSymbol *pFunc, IDiaSession *pSession)
{
IDiaEnumLineNumbers* pEnum = NULL;
DWORD rva;
ULONGLONG length;
if (pFunc->get_relativeVirtualAddress ( &rva ) == S_OK)
{
pFunc->get_length ( &length );
pSession->findLinesByRVA( rva, static_cast<DWORD>( length ), &pEnum );
}
return(pEnum);
}
