Name
       syslog, openlog, closelog - control system log

Syntax
       #include <syslog.h>

       openlog(ident, logstat)
       char *ident;

       void syslog(priority, message, parameters ... )
       char *message;

       void closelog()

Description
       The  subroutine	arranges  to  write  the message onto the system log maintained by The message is tagged with priority and it looks like a
       string except that %m is replaced by the current error message (collected from A trailing new line is added if  needed.	 This  message	is
       read by and output to the system console or files as appropriate.  The maximum number of parameters is 5.

       If  special  processing is needed, can be called to initialize the log file.  Parameters are ident which is prepended to every message, and
       logstat which is a bit field indicating special status; current values are:

       LOG_PID	log the process id with each message; useful for identifying daemons.

       The returns zero on success.  If it cannot open the file it writes on instead and returns -1.

       The can be used to close the log file.

Examples
       syslog(LOG_SALERT, "who: internal error 23");

       openlog("serverftp", LOG_PID);
       syslog(LOG_INFO, "Connection from host %d", CallingHost);

openlog - Open connection to system logger

SYNOPSIS

       bool openlog (string  $ident, int  $option, int	$facility)

DESCRIPTION

       openlog(3) opens a connection to the system logger for a program.

	The use of openlog(3) is optional. It will automatically be called by syslog(3) if necessary, in which case $ident will default to FALSE.

PARAMETERS

	      o $ident
		- The string $ident is added to each message.

	      o $option
		- The $option argument is used to indicate what logging options will be used when generating a log message.

	      +-----------+---------------------------------------------------+
	       You can use one or more of this options. When using multiple options you need to OR them, i.e. to open the connection  immediately,
	      write to the console and include the PID in each message, you will use: LOG_CONS | LOG_NDELAY | LOG_PID

	      o $facility
		-  The	$facility  argument  is  used  to specify what type of program is logging the message. This allows you to specify (in your
		machine's syslog configuration) how messages coming from different facilities will be handled.
