myvsyslog.c

基于TCP-WRAP原理的系统监控的c语言实现代码

 /*
  * vsyslog() for sites without. In order to enable this code, build with
  * -Dvsyslog=myvsyslog. We use a different name so that no accidents will
  * happen when vsyslog() exists. On systems with vsyslog(), syslog() is
  * typically implemented in terms of vsyslog().
