query the properties of a sync object Signature glGetSync

(

sync , pname , bufSize = 1 , length = None , values = None

)

Wrapper around glGetSynciv that auto-allocates buffers
    
    sync -- the GLsync struct pointer (see glGetSynciv)
    pname -- constant to retrieve (see glGetSynciv)
    bufSize -- defaults to 1, maximum number of items to retrieve,
        currently all constants are defined to return a single 
        value 
    length -- None or a GLint() instance (ONLY!), must be a byref()
        capable object with a .value attribute which retrieves the 
        set value
    values -- None or an array object, if None, will be a default 
        return-array-type of length bufSize
    
    returns values[:length.value], i.e. an array with the values set 
    by the call, currently always a single-value array.
