FBB::SyslogBuf(3bobcat) 				     Stream Buffer for Syslog					   FBB::SyslogBuf(3bobcat)

NAME

       FBB::SyslogBuf - A streambuf object inserting syslog messages

SYNOPSIS

       #include <bobcat/syslogbuf>
       Linking option: -lbobcat

DESCRIPTION

       FBB::SyslogBuf objects may be used as a std::streambuf of std::ostream objects to write syslog messages using stream facilities.

NAMESPACE

       FBB
       All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

INHERITS FROM

       std::streambuf

ENUMERATIONS

       The following enumerations are defined in the namespace FBB:

       Priority:

       The values of this enumeration match the corresponding priority LOG_xxx values used with syslog(3):

       o      EMERG:
	      system is unusable;

       o      ALERT:
	      action must be taken immediately;

       o      CRIT:
	      critical conditions;

       o      ERR:
	      error conditions;

       o      WARNING:
	      warning conditions;

       o      NOTICE:
	      normal, but significant, condition;

       o      INFO:
	      informational message;

       o      DEBUG:
	      debug-level message;

       Facility:

       The values of this enumeration match the corresponding facility LOG_xxx values used with syslog(3):

       o      AUTHPRIV:
	      security/authorization messages (private)

       o      CRON:
	      clock daemon (cron and at)

       o      DAEMON:
	      other system daemons

       o      KERN:
	      kernel messages

       o      LOCAL0:
	      reserved for local use. LOCAL1 through LOCAL7 are available as well.

       o      LPR:
	      line printer subsystem

       o      MAIL:
	      mail subsystem

       o      NEWS:
	      USENET news subsystem

       o      SYSLOGBUF:
	      messages generated internally by syslogbufd

       o      USER:
	      generic user-level messages

       o      UUCP:
	      UUCP subsystem

CONSTRUCTOR

       o      SyslogBuf(char *ident, FBB::Priority priority = FBB::NOTICE, FBB::Facility facility = FBB::USER, int option = 0):
	      This  Syslogbuf()  constructor  initializes the streambuf.  The ident parameter is usually the name of the program. Its contents are
	      prepended to syslog messages. Use value 0 if no text needs to be prepended.

	      The priority parameter determines the importance of the message. By default FBB::NOTICE is used.

	      The facility parameter determines the type of program doing the logging. By default FBB::USER is used.

	      The option parameter may be used to specify various options (use the binary `bitor' (`|') operator to combine options):

	      LOG_CONS: write directly to system console  if  there  is  an error while sending to system logger
	      LOG_NDELAY: open the connection immediately (normally, the con- nection is opened when the first message is logged)
	      LOG_PERROR: print to stderr as well
	      LOG__PID: include PID with each message

	      By default no options are used.

       The copy constructor is not available.

MEMBER FUNCTIONS

       All members of std::streambuf are available, as FBB::SyslogBuf inherits from this class.

       o      Priority defaultPriority() const:
	      Returns the default priority. I.e., the priority that will be used for the messages after inserting endl, unless altered	by  setDe-
	      faultPriority().

       o      Priority priority() const:
	      Returns the next priority. I.e., the priority that will be used for the next message, unless altered by setPriority().

       o      Priority setDefaultPriority(Priority priority):
	      Changes  the  default  priority  of  the next syslog-message after inserting std::eoln. Initially, the priority is determined as the
	      value passed to the constructor. The previously active default priority is returned.

       o      Priority setPriority(Priority priority):
	      Changes the priority for the next syslog message (after std::eoln has been inserted). Subsequent messages will use the default  pri-
	      ority again. The previously active priority setting is returned.

PROTECTED MEMBER FUNCTION

       The member listed in this section implements the tasks of the comparably named virtual function in the class's private interface. This sep-
       arates the redefinable interface from the user-interface. The class Syslogbuf can, in accordance with Liskov's Substitution  Principle,	be
       used as a std:streambuf; but it also offers a facility for classes deriving from Syslogbuf. This facility is listed here.

       o      int pSync():
	      The contents of the Syslogbuf's internal buffer is flushed.

EXAMPLE

       See also syslogstream(3bobcat)

       #include <iostream>
       #include <bobcat/syslogbuf>

       using namespace std;
       using namespace FBB;

       int main(int argc, char **argv)
       {
	   ostream sls(new SyslogBuf(argv[0]));

	   sls << SyslogStream::debug << "Hello world" << endl;
	   sls << SyslogStream::strerrno << endl;

	   return 0;
       }

BUGS

       The  constructor's option parameter is an int. Because of this, int values rather than enumeration values are passed to the constructor. It
       is the responsibility of the programmer to pass defined option values only.
