Indicate number of samples available per channel in engine
Note: You cannot use the legacy interface on 64-bit MATLAB®. See About the Session-Based Interface to acquire and generate data on a 64-bit MATLAB.
For analog input (AI) objects,
the number of samples that can be extracted from the engine for each
channel group member with the
For analog output (AO) objects,
the number of samples that have been queued with the
and can be sent (output) to each channel group member.
After data has been extracted (AI) or output (AO), the
is reduced by the appropriate number of samples. For AI objects,
reset to zero after a
start function is issued.
For AI objects, use the
to find out how many samples have been acquired since the
was issued. For AO objects, use the
to find out how many samples have been output since the
AI, AO, common to all channels

The value is automatically updated based on the number of samples acquired (analog input) or sent (analog output). The default value is zero.
