YOpenConnection (3)

Name

YOpenConnection - connect to Y server

Syntax

#include <Y2/Y.h>
#include <Y2/Ylib.h>

YConnection *YOpenConnection(
const char *start_arg,
const char *con_arg
)

Arguments

start_arg
Specifies the null terminated command to be executed to start the Y server. This command is only used if the Y server does not appear to be currently running. If you do not want the Y server to be started if it is not running, then just pass NULL.

con_arg
Specifies the connect argument to connect to the Y server. The format is a null terminated string of the format “<address>:<port>” where <address> specifies the address of the Y server and <port> specifies the port number it is polling for incoming connections on. An example connect argument would be “127.0.0.1:9433” which would connect to localhost on port 9433 (standard port number).

Description

The YOpenConnection opens a new connection to the Y server.

Return Value

The YOpenConnection returns a YConnection pointer that serves as the connection to the Y server and that contains all the information about that Y server. It can also return NULL if it failed to start the Y server (as needed or requested) and/or connect to it.

Example

#include <stdio.h>
#include <Y2/Y.h>
#include <Y2/Ylib.h>

int main(int argc, char *argv[])
{
YConnection *con = YOpenConnection( “/usr/sbin/starty",
“127.0.0.1:9433"
);
if(con == NULL)
return(1) ;

YCloseConnection(con, False);

return(0);
}
