As others have said if you want to "guarantee" that your "message" is delivered to the application at the other end, you need to move beyond relying on the network protocol. There are a number of middleware messaging protocols which can provide this guarantee. AMQP is one, others include JMS, IBM's MQSeries and Tibco's Rendezvous.

socket_connect4
socket_connect4(3) Library Functions Manual socket_connect4(3)
NAME
socket_connect4 - attempt to make a TCP connection
SYNTAX
#include <socket.h>
int socket_connect4(int s,const char ip[4],uint16 port);
DESCRIPTION
socket_connect4 attempts to make a connection from TCP socket s to TCP port port on IP address ip.
socket_connect4 may return
o 0, to indicate that the connection succeeded (and succeeded immediately, if the socket is non-blocking)
o -1, setting errno to error_inprogress or error_wouldblock, to indicate that the socket is non-blocking
o -1, setting errno to something else, to indicate that the connection failed (and failed immediately, if the socket is non-blocking).
When a background connection succeeds or fails, s becomes writable; you can use socket_connected to see whether the connection succeeded.
If the connection failed, socket_connected returns 0, setting errno appropriately.
Once a TCP socket is connected, you can use the read and write system calls to transmit data.
You can call socket_connect4 without calling socket_bind4. This has the effect as first calling socket_bind4 with IP address 0.0.0.0 and
port 0.
EXAMPLE
#include <socket.h>
int s;
char ip[4];
uint16 p;
s = socket_tcp4();
socket_bind4(s,ip,p);
socket_connect4(s,ip,p);
