/*
 * igetevent.c
 *
 * This utility waits for IPMI Event Messages.
 * Some server management functions want to trigger custom actions or 
 * alerts when IPMI hardware-related events occur, but do not want to
 * track all events, just newly occurring events.
 * The IPMI events also include BIOS events such as Memory and POST errors,
 * which would not be captured by reading the IPMI sensors.
 * This utility waits a specified timeout period for any events, and 
 * returns interpreted output for each event.  It is designed as a
 * scriptable command-line utility, but if the timeout is infinite
 * (-t 0), then this code could be used for a sample service as well.
 *
 * There are several methods to do this which are implemented here.
 * The SEL method (-s):     
 *    This method polls the SEL once a second, keeps track of the last 
 *    SEL event read, and only new events are processed.  This ensures 
 *    that in a series of rapid events, all events are received in order, 
 *    however, some transition-to-OK events may not be configured to 
 *    write to the SEL on certain platforms.  
 *    This method is used if getevent -s is specified.
 * The ReadEventMessageBuffer method (-m getmessage option): 
 *    This uses an IPMI Message Buffer in the BMC firmware to read
 *    each new event.  This receives any event, but if two events 
 *    occur nearly simultaneously, only the most recent of the two 
 *    will be returned with this method.  An example of simultaneous 
 *    events might be, if a fan stops/fails, both the non-critical 
 *    and critical fan threshold events would occur at that time.
 *    This is the default method for getevent.  It would be used 
 *    locally with the Intel IMB driver or with direct/driverless.
 * The OpenIPMI custom method (-m getmessage_mv option if DRV_MV):  
 *    Different IPMI drivers may have varying behavior.  For instance,
 *    the OpenIPMI driver uses the IPMI GetMessage commands internally 
 *    and does not allow client programs to use those commands.  It has 
 *    its own custom mechanism, see getevent_mv().
 *    This method is used locally if the OpenIPMI driver is detected.
 * The Async Event method (-a):
 *    This only gets certain Asynchronous events, like a shutdown 
 *    request from the BMC to an SMS OS service, and get_software_id.
 *    This is supported for Intel IMB driver and OpenIPMI driver only.
 *    This method is only used locally if getevent option -a is used,
 *    and if either MV (openipmi) or IMB driver is loaded.
 *    The ipmiutil_asy init script controls the getevent -a service.
 *    (see DO_ASYNC compile flag comments)
