    Subjectselect() on /dev/input/eventX not level-triggered?
    Hi!

    I'm debugging strange behaviour on /dev/input/eventX ... it seems that
    select is not behaving level-triggered as it apparently should. I can
    reproduce it when hitting windows & alt keys.

    Now, I really should rewrite it into C, first, but perhaps someone has
    an idea?

    import struct
    import time
    import select
    import os
    import random

    #
    # format of the event structure (int, int, short, short, int)
    inputEventFormat = 'iihhi'
    inputEventSize = 16
    file = open("/dev/input/event5", "rb") # standard binary file input
    while 1:
    ( i, o, e ) = select.select( [file], [], [], 0.5 )
    if i == []:
    print "timeout event"
    continue
    event = file.read(inputEventSize)
    time.sleep(1)
    (time1, time2, type, code, value) = struct.unpack(inputEventFormat, event)
    print "type ", type, " code ", code, " value ", value

    file.close()
