time_event结构体typedef struct timed_event_struct{ int event_type; time_t run_time; int recurring; unsigned long event_interval; int compensate_for_time_change; void *timing_func; void *event_da

记录一下学习nagios过程中的点点滴滴

skiplistnode结构体typedef struct skiplistnode_struct{ void *data; struct skiplistnode_struct *forward[1];}skiplistnode;data用于存放指向实际数据的指针forward[]为一个指针数组，forward[i]中的i值对应跳跃表中的一层，如果本skiplistnode

nagios的文件是nagios.c是main函数所在的文件#ifdef EMBEDDEDPERLint main(int argc, char **argv, char **env){#elseint main(int argc, char **argv){#endifEMBEDDEDPERL用来标识是否将内置的perl支持进行编译接下来为一些局部变量的定义

int my_free(void **ptr){ if(ptr==NULL) return ERROR; /* I hate calling free() and then resetting the pointer to NULL, so lets do it together */ if(*ptr){
