tibrvftMonitorCallback

Function Type

Declaration

typedef void (*tibrvftMonitorCallback) (
    tibrvftMonitor       monitor,
    const char*          groupName,
    tibrv_u32            numActiveMembers,
    void*                closure);

Purpose

Process fault tolerance events for a monitor.

Remarks

A program must define a function of this type as a prerequisite for monitoring a fault tolerance group. Programs register a monitor callback function with each call to tibrvftMonitor_Create().

Rendezvous fault tolerance software queues a monitor event whenever the number of active members in the group changes.

A program need not be a member of a group in order to monitor that group. Programs that do not monitor need not define a monitor callback function.

Parameter	Description
monitor	This parameter receives the monitor object.
groupName	This parameter receives a string denoting the name of the fault tolerance group.
numActiveMembers	This parameter receives the number of group members now active.
closure	This parameter receives the closure data, which the program supplied in the call that created the monitor object.
