How to log messages in LINUX/UNIX using SYSLOG

The is a special logging framework available in UNIX call as SYSLOG. In this example, we will see how can we log an INFO to syslog

#include <stdio.h>
#include <unistd.h>
#include <syslog.h>

int main(void) {

 openlog("mySYSLOG", 0, LOG_USER);
 syslog(LOG_INFO, "HELLO WORLD...LOG THIS MESSAGE");
 closelog();
 return 0;
}

First we have to include <syslog.h> header file. Then we need to open a connection by using the openlog function.Finally we need to log the message by using the syslog function. The syslog function acts like the PRINTF function of C language.
Hope this helps.
