then there is someone can point out some C program for the use api
"ReadFile" with an handle return by api "socket"?

thank you

the problem is that if i have a tcp sever istalled in the port 1000 in
my computer, and "cli.exe" is the C program "client program" below and
type

cli 127.1.1.1 1000

connect of client fail with "WSAECONNREFUSED 10061"
don't understand why

there is someone expert in this there?
what is the answer?

then there is someone can point out some C program for the use api
"ReadFile" with an handle return by api "socket"?

thank you
