Eagerly waiting for your reply.
Eagerly waiting for your explanation of what you mean by "break".
Do you mean "to interrupt normal reading"?
Do you mean "to separate into sections"?
Do you mean something else?
Please describe what you are doing with the read stream, and what you
want to accomplish. Then describe what "break" means in reference to
the rest of what you are doing.

Hi GG,
Thanks for your reply.
In your mailing list, you suggest me demonstrating what I want to do,
so now I am describing it in detail, please see below.
I want to receive data from FTP servers over a network with CFFTP API,
and can safely stop transferring data at any time.
Firstly, create the stream using CFReadStreamCreateWithFTPURL().
Secondly, set up my callbacks with CFReadStreamSetClient().
Thirdly, add it to the run-loop with
CFReadStreamScheduleWithRunLoop().
Finally, open the stream with CFReadStreamOpen().
I'll get call-backs when information is available to be read.
I can accomplish receiving data from FTP servers successfully.
When transferring data, I stop it using
CFReadStreamUnscheduleFromRunLoop()
and CFReadStreamClose().
When I am resuming to connect the same file in FTP servers, I always
get
the same problem which show error code 530 that meams user not
logged in.
However, I can connect other files in FTP servers successfully.
I guess the reason why I can not connect the same file again is that
I did not
interupt the read stream safely.
So my question is...How can I resume to connect and receive data
from the same file
in FTP servers or how can I interupt the read stream safely.
Here is my msn identifier [email protected] if you could add me.
Waiting for your reply.
Best Regards,
Chris.
