Comment: these variables have been set as an example and can be any valid value.
pParameter will be set true by your callback function lpReady.
while (!pParameter) Sleep (0);

for (int c = PS3000A_CHANNEL_A; c <= PS3000A_CHANNEL_B; c++)

);
}
}
Comments: buffer has been created as a two-dimensional array of pointers to shorts,
which will contain 1000 samples as defined by MAX_SAMPLES. There are only 10
buffers set, but it is possible to set up to the number of captures you have requested.
