RE: SETSOCKOPT question

Hi Kevin,

Yes fun with HL7.

When you need to test for certain strings that you
receive over a socket connection, you should always have two buffers and
never check the one that gets the bytes from the socket. Read from the
socket and then append the number of bytes read to a holding buffer.
Check the holding buffer for the end message you are looking for. If
you don't find you string, loop back and read some more bytes and then
append them to the holding buffer and check again. You will have to
keep track of where you are in the holding buffer as you move data in
and out of it, but that is only real way to deal with streaming data.


Actually I do read from the buffer and append it the data read to a
variable length field. But I understand your point. Thanks for the input.

Regards, Jerry
