DhcpNotifyConfigChange运行失败！？

Question

BOOL (*pDhcpNotifyProc)(LPWSTR,LPWSTR,BOOL,DWORD,DWORD,DWORD,int);
pDhcpNotifyProc=(BOOL(*)(LPWSTR,LPWSTR,BOOL,DWORD,DWORD,DWORD,int))GetProcAddress(hDhcpDll,"DhcpNotifyConfigChange"))
pDhcpNotifyProc(NULL,pApp->m_pNameOfAdapter,(BOOL)TRUE,(DWORD)0,(DWORD)inet_addr(chrNet),(DWORD)inet_addr("255.255.255.0"),2)；首先，pDhcpNotifyProc已经成功获得了该函数的地址，其它参数也完全正确

Answer 1

dll中的函数是这样的:
 int __stdcall DhcpNotifyConfigChange(int,wchar_t *,int,int,int,int,int)

Answer 2

改成int __stdcall DhcpNotifyConfigChange(int,wchar_t *,int,int,int,int,int)
也错

Answer 3
