关于VC中FTP上传！

[wuleeemail]

用VC做了一个程序，当中带着一些FTP的，做好以后发现FTP到对方三个子目录内都可以，如果超过三个就失败了。搞得很郁闷。不知道哪位知道在VC中代码如何写才能保证FTP进入多少个子目录都可以？ 谢了！

进入当前目录，下载，再进入下一目录下载。
ftp协议里，进入另一目录是有命令的.

static int FtpXfer(const char *localfile, const char *path,
netbuf *nControl, int typ, int mode)
{
int l,c;
char *dbuf;
FILE *local = NULL;
netbuf *nData;
int rv=1;

if (localfile != NULL)
{
char ac[4] = "w";
if (typ == FTPLIB_FILE_WRITE)
ac[0] = 'r';
if (mode == FTPLIB_IMAGE)
ac[1] = 'b';
local = fopen(localfile, ac);
if (local == NULL)
{
strncpy(nControl->response, strerror(errno), sizeof(nControl->response));
return 0;
}
}
if (local == NULL)
local = (typ == FTPLIB_FILE_WRITE) ? stdin : stdout;
if (!FtpAccess(path, typ, mode, nControl, &nData))
return 0;
dbuf = malloc(FTPLIB_BUFSIZ);
if (typ == FTPLIB_FILE_WRITE)
{
while ((l = fread(dbuf, 1, FTPLIB_BUFSIZ, local)) > 0)
if ((c = FtpWrite(dbuf, l, nData)) < l)
{
printf("short write: passed %d, wrote %d\n", l, c);
rv = 0;
break;
}
}
else
{
while ((l = FtpRead(dbuf, FTPLIB_BUFSIZ, nData)) > 0)
if (fwrite(dbuf, 1, l, local) <= 0)
{
perror("localfile write");
rv = 0;
break;
}
}
free(dbuf);
fflush(local);
if (localfile != NULL)
fclose(local);
FtpClose(nData);
return rv;
}

保证路径正确的情况下，VC是没有路径个数限制的。
