Hi,
I had a question regarding non-blocking read in a TCP socket program.
I have the code below.
The non-blocking code works, but, I see that the "perror("Read");" in my
server returns "Resource temporarily unavailable" instead of "success".
Is this normal?
Also, when my client closes the connection, I do not get "Connection reset
by peer" at my server. This happens for both blocked read and non-block
read. In this case, the server reads 0 bytes and goes into a infinite
loop. Shouldn't I get a ECONNRESET in this case?
TIA,
Pramodh
server code
-----------------
newsockfd = accept(sockfd,(struct sockaddr *)&client,&clilen);
ioctl(newsockfd, FIONBIO, (char *)&arg);
while (1) {
if ((len = read(newsockfd, buff, 2)) < 0) {
perror("Read error:");
sleep(2);
continue;
}
perror("Read");
}
-------------------------------
client code
---------------------
connect(sockfd,(struct sockaddr *)&server,sizeof(struct sockaddr_in));
writes 5 times {
len = write(sockfd,buff,10);
sleep(5);
}
---------------------------------
