hi all,

is there a way to make a connect block? iow, what status has the
server to be in to make a connect block? in the state bound the connect
fails, in the state listen the connect succeeds, even without accept.
system is solaris 9.

thanks for any reply.

connect() blocks by default.

What I *think* you're asking about is a way to make the server side
avoid sending SYN-ACK until accept() is called. No, there's no way to
do that on Solaris (or most systems for that matter). The kernel
manages the connection queue on listen sockets.

Thanks for replying James. You were *thinking* right. I expected with
a server having a listen(fd,2) and not accepting, the third connect to
block
but it does not. Apparently I am confused aout the meaning of the
second parameter
of the listen() system call.

It's a limit on the number of completed connections waiting to be
accepted by the application.
