This function is used to get values in compatible streaming mode after calling
ps2000_run_streaming, or in block mode after calling ps2000_run_block.
Note that if you are using block mode or ETS mode and call this function before the
oscilloscope is ready, no capture will be available and the driver will not return any
samples.
Compatible streaming mode and block mode only
Does nothing if ETS triggering is enabled. Use
ps2000_get_times_and_values instead.
Do not use in fast streaming mode. Use
ps2000_get_streaming_last_values instead.
handle: the handle of the required oscilloscope
buffer_a, buffer_b: pointers to the buffers that receive data
from the specified channels (A and B). A pointer is not used if the
oscilloscope is not collecting data from that channel. If a pointer is
NULL, nothing will be written to it.
buffer_c, buffer_d: not used
overflow: on exit, contains a bit pattern indicating whether an
overflow has occurred and, if so, on which channel. Bit 0 is the least
significant bit. The bit assignments are as follows:
Bit 0 - Ch A overflow
Bit 1 - Ch B overflow
no_of_values: the number of data points to return. In streaming
mode, this is the maximum number of values to return.
The actual number of data values per channel returned, which may
be less than no_of_values if streaming
0: if one of the parameters is out of range or the oscilloscope is not
in a suitable mode
