TCHAR行尾字符

Question

int DownloadFtpDirectory(TCHAR* DirPath) { 
WIN32_FIND_DATA FileData;  
UINT a; 
TCHAR* APP_NAME = TEXT("ftpcli"); 
TCHAR* f;
int j = 5;
do {
  j++;
  f = _tcsninc(DirPath, j);
}while (_tcsncmp(f, TEXT("/"), 1));
TCHAR* PATH_FTP = wcsncpy(new TCHAR[j], DirPath, j);

在最后一行得到一个没有行结束字符的字符串后，如何解决这个问题？附注:如果两个字符串都是TCHAR，怎么做会超出行"ftp://ftp.microsoft.com/bussys/"，得到一个字符串ftp.microsoft.com？

Answer 1

TCHAR* PATH_FTP = wcsncpy(new TCHAR[j+1], DirPath, j);
PATH_FTP[j] = TEXT('\0');
