    lws_snprintf(): snprintf that truncates the returned length too

    +
    Parameters
    + + + + + +
    strdestination buffer
    sizebytes left in destination buffer
    formatformat string
    ...args for format
    +
    +
    +

    This lets you correctly truncate buffers by concatenating lengths, if you reach the limit the reported length doesn't exceed the limit.
