Function Documentation

int addLogHook (  hookfn_t  hf  ) 
 

addLogHook adds a pointer to a hook function to the list of log hooks to be called during the process of scanning logs. This is to allow loadable modules to hook into the log scanning process.

int addLoopHook (  loopfn_t  hf  ) 
 

addLoopHook adds a pointer to a loop hook function to the list of loop hooks to be called during the process of scanning logs. This is to allow loadable modules to hook into the main execution loop
