monitor

VCSAgResState
res_monitor(const char *res_name, void **attr_val,int *conf_level);

You may select any name for the function.

The parameter conf_level is an output parameter. The return value, which indicates the resource status, must be a defined VCSAgResState value. See Summary of Return Values for Entry Points.

The monitor field of VCSAgV40EntryPointStruct passed to VCSAgRegisterEPStruct() must be assigned a pointer to this function.

For example:

#include "VCSAgApi.h"

VCSAgResState
res_monitor(const char *res_name, void **attr_val, int *conf_level)
{

  // Code to determine the state of a resource.
  VCSAgResState res_state = ...
  if (res_state == VCSAgResOnline) {
   // Determine the confidence level (0 to 100).
   *conf_level = ...
  }
  else {
    *conf_level = 0;
  }
  return res_state;
}
void VCSAgStartup() {
  VCSAgV40EntryPointStruct ep;
  ...
  ep.monitor =  res_monitor;
  ...
  VCSAgRegisterEPStruct(V40, &ep);
}
