def samples_available(self):
return lib.lsl_samples_available(self.obj)<EOL>
Query whether samples are currently available for immediate pickup.

        Note that it is not a good idea to use samples_available() to determine 
        whether a pull_*() call would block: to be sure, set the pull timeout 
        to 0.0 or an acceptably low value. If the underlying implementation 
        supports it, the value will be the number of samples available 
        (otherwise it will be 1 or 0).
