i.MXRT 1052 - LPUART_RTOS_Receive() API issues

[suhel_mulla]

I am working of Freertos based LPUART example from SDK on  NXP i.MXRT 1050 EVK board .

I have following queries - 

1. Is their any document / post having detailed dexplanation of LPUART_RTOS_Receive(lpuart_rtos_handle_t *handle, uint8_t *buffer, uint32_t length, size_t *received) API. What is the significance of the argument size_t *received.

2. What is the difference between ring buffer overflow & hardware buffer overflow?

3. When hardware buffer overflow occurs?

I have attached the .c file having LPUART_RTOS_Receive() API definition for reference.
