Importing a C++ function problems

Hi, I have this C++ function:

bool CreateDirectoryUserFullAccess(LPCTSTR lpPath)
{
int f = CreateDirectory(lpPath,NULL);
if(!f)
return false;

HANDLE hDir = CreateFile(lpPath,READ_CONTROL|WRITE_DAC,0,NULL,OPEN_EXISTING,FILE_FLAG_BACKUP_SEMANTICS,NULL);
if(hDir == INVALID_HANDLE_VALUE)
return true;

ACL* pOldDACL=NULL;
SECURITY_DESCRIPTOR* pSD = NULL;
GetSecurityInfo(hDir,SE_FILE_OBJECT,DACL_SECURITY_INFORMATION,NULL,NULL,&pOldDACL,NULL,(void**)&pSD);

EXPLICIT_ACCESS ea={0};
ea.grfAccessMode = GRANT_ACCESS;
ea.grfAccessPermissions = GENERIC_ALL;
ea.grfInheritance = CONTAINER_INHERIT_ACE|OBJECT_INHERIT_ACE;
ea.Trustee.TrusteeType = TRUSTEE_IS_GROUP;
ea.Trustee.TrusteeForm = TRUSTEE_IS_NAME;
ea.Trustee.ptstrName = TEXT("Users");

ACL* pNewDACL = NULL;
SetEntriesInAcl(1,&ea,pOldDACL,&pNewDACL);

SetSecurityInfo(hDir,SE_FILE_OBJECT,DACL_SECURITY_INFORMATION,NULL,NULL,pNewDACL,NULL);

LocalFree(pSD);
LocalFree(pNewDACL);
CloseHandle(hDir);
return true;
}

Save in a file called vista.cpp

Then in Bmax I go:

Strict

Import "vista.cpp"

But when I compile, I get a page full of errors like this:

I've NO idea where to start. I must be doing something really basic wrong. Any ideas? Thanks.

Oh an dI tried saving the file as .c and importing that but got similar errors.
