how is the data in the adc pool updated and emptied

In version 5.1 of esp-idf, how is the data in the adc pool updated and emptied. I hope you can help me answer, thank you

In ESP-IDF, the ADC pool is typically used to store ADC conversion results in continuous mode or DMA mode. When the ADC is configured to sample continuously, the ADC driver updates the ADC pool with new conversion results at a defined sampling rate. When the pool is full, new samples will start overwriting the older ones, and you can access the ADC data from the pool for further processing.

when internal pool is full [...] [n]ewer conversion results will be discarded.
