problem accessing api from Delphi

Hi,

I'm working on this Delphi program which required to call some function from an API, which written in C++. The functions that I want to call are in someDLL.dll. When I tried to register the .dll, I get the error: "someDLL.dll was loaded, but the DllRegisterServer entry point was not found ..."

When I ran the Delphi program, I get the error: "The procedure entry point Some_Function could not be located in the dynamic link library someDLL.dll. I've the .dll file in the same folder as the .exe.

Can somebody tell me what is wrong here, pls.

Many thanks
