IDiaSession::findILOffsetsByVA

  • Article

Retrieves an enumeration that allows a client to iterate through the MSIL offsets within a specified address range.

Syntax

HRESULT findILOffsetsByVA (
    ULONGLONG va,
    DWORD length,
    IDiaEnumLineNumbers** ppResult
);

Parameters

va

[in] Specifies the address as a VA.

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 MSIL offsets 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 MSIL offset contained in a function using the function's address and length.

IDiaEnumLineNumbers* GetLineNumbersByAddr(IDiaSymbol *pFunc,
                                          IDiaSession *pSession)
{
    IDiaEnumLineNumbers* pEnum = NULL;
    ULONGLONG            va = 0;
    ULONGLONG            length = 0;

    if (pFunc->get_virtualAddress ( &rva ) == S_OK)
    {
        pFunc->get_length ( &length );
        pSession->findILOffsetsByVA( va, static_cast<DWORD>( length ), &pEnum );
    }
    return(pEnum);
}
