Sorry if I posted 2 separate questions.
I'm currently doing socket programming on my current task. As you can see below in the client side. I've tried to do a loop so I will be able to get prompt for input over and over again.
This is the code.
Code:
do{
printf("Please your name > ");
scanf("%s",name);
write(clientFd,name,strlen(name));
}while(strcmp("exit",name)!=0);
It worked for the first time, but the second time it asked me for input but it did not print anything on the server side. After entering the second input it exited from the terminal.
I've check up the loop and realize it was the write problem. Any way to solve this?
Suppose i am writing a C program which is going to use Socket calls. I want to use a Unix port for my Socket.
How can i determine a port which is not already in use? (1 Reply)

Hi,
I have a client-server socket program. It has been working fine for over a year, but recently it started to show strange behavior.:confused:

I'm using C/ C++ with gcc on Linux. I've a server socket where accept() is called on the socket inside a while() loop. The problem I am facing is that the first call to accept is blocking (i.e., the program waits for the first connection) but as soon as I fork afterwards (so that the child process... (2 Replies)
will there be any unexpected results on looping connect call for a non blocking socket to determine the connection based on error code. I am getting connection unsuccessful intermittently and so wondering whether is the timeout 500 millisec not sufficient or looping connect cause any unexpected.

LEARN ABOUT PHP
socket_set_block
SOCKET_SET_BLOCK(3) 1 SOCKET_SET_BLOCK(3)socket_set_block - Sets blocking mode on a socket resourceSYNOPSIS
bool socket_set_block (resource $socket)
DESCRIPTION
The socket_set_block(3) function removes the O_NONBLOCK flag on the socket specified by the $socket parameter.
When an operation (e.g. receive, send, connect, accept, ...) is performed on a blocking socket, the script will pause its execution until
it receives a signal or it can perform the operation.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
socket_set_block(3) example
<?php
$socket = socket_create_listen(1223);
socket_set_block($socket);
socket_accept($socket);
?>
This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_BLOCK mode. socket_accept(3) will
hang until there is a connection to accept.
