Here is an example of openlog
, syslog
, and closelog
:
This example sets the logmask so that debug and informational messages
get discarded without ever reaching Syslog. So the second syslog
in the example does nothing.
#include <syslog.h> setlogmask (LOG_UPTO (LOG_NOTICE)); openlog ("exampleprog", LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1); syslog (LOG_NOTICE, "Program started by User %d", getuid ()); syslog (LOG_INFO, "A tree falls in a forest"); closelog ();@set mult · @set infty ∞ @set pie π
@macro mul @cdot @macro infinity @infty @ifnottex @macro pi
