C++Builder based dll library: how to import to Delphi?

[erft]

Dear All,

perhaps you have some experience in the following matter:
I've designed a simple dll library using BC++Builder. It is obviously written in C++. Now, I want it to become a part of larger project that is written in Delphi.
Unfortunately Delphi's compiler says it cannot find functions that are within my dll.
Do you know how should I modify my dll in order to import it to Delphi project?

Thank you in advance.

use cdecl in the interface declaration.
use a underscore on start of the name.
check the names case sensitivity
i.e.

interface
function _MyFunction(pszName: PChar): Boolean;cdecl;

implementation
function _MyFunction(pszName: PChar): Boolean;cdecl;external 'Mydll.dll';
