Not find XPE_Shutdown function!

[LittlePK]

I copy the three files:XPEPM.h,XPEPM.lib,XPEPM.dll from XP
Embedded installation media to my application folder.And
then I add the XPEPM.h and XPEPM.lib files to my
application project using visual c++6.I call the
XPE_Shutdown function in my application.But When I build
it,it shows error:
error LNK2001: unresolved external symbol "unsigned long
__stdcall XPE_Shutdown(void)" (?XPE_Shutdown@@YGKXZ)

Why can not it find the function?

I have already resolved.I use the function of xpepm.dll
with explicit linking.
