Hi, all -
I am trying to write both sever/client that using non blocking socket.
I am not using BIO based read/write. Here is what my code look like - The
code is almost
same as the serv.cpp and cli.cpp under demos/ssl, except I am seting non
blocking
option (O_NONBLOCK)
SERVER:
========
SSL *ssl;
SSL_CTX *ctx;
listen_sd = socket(..)
flag = fcntl(listen_sd, F_GETFL);
fcntl(listen_sd, F_SETFL, flag | O_NONBLOCK);
bind(listen_sd, ...);
listen(listen_sd,...);
select(listen_sd+1, ...);
sd = accept(listen_sd, ...);
flag = fcntl(sd, F_GETFL);
fcnt(sd, F_SETFL, flag | O_NONBLOCK);
ctx = SSL_CTX_new(...);
ssl = SSL_new(ctx);
SSL_set_fd(ssl, sd);
SSL_accept(ssl);
for (;;) {
SSL_read(ssl);
SSL_write(ssl);
}
CLIENT:
======
sd = socket(...);
flag = fcntl(sd, F_GETFL);
fcnt(sd, F_SETFL, flag | O_NONBLOCK);
connect(sd,...);
ctx = SSL_CTX_new(...);
ssl = SSL_new(ctx);
SSL_set_fd(ssl, sd);
SSL_connect(ssl);
SSL_write(ssl);
SSL_read(ssl);
The problem is that SSL_accept() failed (return -1). I could not get error
code witn ERR_print_errors and I
don't know why. Does anyone know what's wrong with this piece of code or if
it makes sense? The reason
I am not using BIO is that I would like to manage both non-SSL and SSL
connection over the socket.
Can I do something like that? Any help is appreciated.
Miha
