Re: Socket Programming



fixed

Victor,

Actually a sleep wouldn't be needed if select() was used with a
timeout value. rfc5321
states that the client should give the server 10 minutes to process
information after the DATA portion of the email ends.

I've run across an RPG program that uses socket APIs to send an email. Once
the socket is setup and opened, the program uses a subroutine to do all the
send/receive functions. Just after the send, the subroutine runs the sleep
API with a parameter of 1 second. It appears the original intent was to
give the email server and/or network time to produce/deliver a response
before the receive API runs. Does anyone think this built in delay is
really necessary? Depending on what is being sent, this program can run for
a very long time with these roughly 1 second delays. Also, the program
doesn't do anything with the received data collected after the send API. Is
it really necessary to do a receive after a send? Seems I can tighten this
up a bit.

Thanks,

Vic
