Syslog functions

[chinmay.sahoo]

The syslog functions allow you to open the system log for a program, generate a message,and close it again.

✦ openlog([ident], option, facility) is entirely optional when used with syslog().The ident value is generated automatically.
✦ syslog(priority, message) generates a system log entry.
✦ closelog() is entirely optional when used with syslog(). It takes no arguments.
