NAME

       synce_error - error reporting functions

SYNOPSIS

       #include <synce_log.h>

       void _synce_log(int level, const char* file, int line, const *char format, ... );

       void synce_error(const *char format, ... );
       void synce_warning(const *char format, ... );
       void synce_info(const *char format, ... );
       void synce_debug(const *char format, ... );
       void synce_trace(const *char format, ... );

       void synce_warning_unless(bool condition, const *char format, ... );

       void synce_log_set_level(int level);

       void synce_log_use_syslog(void);

DESCRIPTION

       The  various  synce_xxx() logging functions are implemented as macros calling the underlying _synce_log function, but are presented here as
       they should be used for clarity. All accept a format string and optional arguements in  the  same  way  as  printf(3).	synce_debug()  and
       synce_trace() are equivalent.

       synce_warning_unless() will only take action if cond evaluates to a false value.

       These  functions will as standard log to stdout.  synce_log_use_syslog() will cause the output to be sent to syslog at the appropriate pri-
       ority.

       synce_log_set_level() sets the maximum priority level that will actually be output, whether to stdout or syslog, with the  default  maximum
       level being warning.

       The following defines are available, their equivalent syslog priorities are also shown.

	      SYNCE_LOG_LEVEL_ERROR	LOG_ERR
	      SYNCE_LOG_LEVEL_WARNING	LOG_WARNING
	      SYNCE_LOG_LEVEL_INFO	LOG_INFO
	      SYNCE_LOG_LEVEL_DEBUG	LOG_DEBUG
	      SYNCE_LOG_LEVEL_TRACE	LOG_DEBUG

       The following are also available for use with synce_log_set_level()

	      SYNCE_LOG_LEVEL_LOWEST
	      SYNCE_LOG_LEVEL_HIGHEST
	      SYNCE_LOG_LEVEL_DEFAULT

NAME

       vsyslog - log message with a stdarg argument list

SYNOPSIS

       #include <syslog.h>
       #include <stdarg.h>

       void vsyslog(int priority, const char *message, va_list ap);

DESCRIPTION

       The vsyslog() function is identical to syslog(3C), except that it is called with an argument list as defined by <stdarg.h> rather than with
       a variable number of arguments.

EXAMPLES

       Example 1 Use vsyslog() to write an error routine.

       The following example demonstrates the use of vsyslog() in writing an error routine.

	 #include <syslog.h>
	 #include <stdarg.h>

	 /*
	  * error should be called like:
	  *   error(pri, function_name, format, arg1, arg2...);
	  */

	 void
	 error(int pri, char *function_name, char *format, ...)
	 {
		 va_list args;

		 va_start(args, format);
		 /* log name of function causing error */
		 (void) syslog(pri, "ERROR in %s.", function_name);
		 /* log remainder of message */
		 (void) vsyslog(pri, format, args);
		 va_end(args);
		 (void) abort( );
	 }

	 main()
	 {
		 error(LOG_ERR, "main", "process %d is dying", getpid());
	 }
