Win32 api for opening and getting data from resource files

I have a project that is compiling into a DLL , and a resource file that I added manually. I'm looking for Win32 API that can help me find resource files and get information and data from them (using C++).

For example - to get the Company Name or the version..

Can anyone help me with it?

Thanks.

call the function below passing TEXT("CompanyName") as lpszVersionType `

#pragma comment(lib, "version.lib")
BOOL GetVersionString(LPCTSTR lpszModuleFileName, LPCTSTR lpszVersionType, LPTSTR lpszVersionString)
{   int i, j;
unsigned long u;
LPTSTR pBlock, pTmpVersion;
TCHAR buf[_MAX_PATH];
BOOL bRet = FALSE;

struct LANGANDCODEPAGE
{   WORD wLanguage;
    WORD wCodePage;
} *lpTranslate;

if ((i = GetFileVersionInfoSize(lpszModuleFileName, &u)) == 0) // !!
    return FALSE;
i++;
pBlock = (LPTSTR)HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, i * sizeof(TCHAR));
if (pBlock == NULL) // !!
    return FALSE;

if (GetFileVersionInfo(lpszModuleFileName, u, i, pBlock))
{   VerQueryValue(pBlock, TEXT ("\\VarFileInfo\\Translation"), (LPVOID*)&lpTranslate, (UINT *)&u); // // Read the list of languages and code pages
    j = (int)(u/sizeof(struct LANGANDCODEPAGE));
    for (i = 0; i < j; i++)
    {   wsprintf(buf, TEXT ("\\StringFileInfo\\%04x%04x\\%s"), lpTranslate[i].wLanguage, lpTranslate[i].wCodePage, lpszVersionType);
        VerQueryValue(pBlock, buf, (void **)&pTmpVersion, (UINT *)&u);
        if (u > 0)
        {   lstrcpy(lpszVersionString, pTmpVersion);
            bRet = TRUE;
            break;
        }
    }
}

HeapFree(GetProcessHeap(), 0, pBlock);

return bRet;
}
