Hey everyone, just like there is a function named "Serial.available()" in Arduino,is there any such function present in STM32 ?

Hi,
No.
btw " in STM32" -> this is cpu series , so library functions cannot be there.
If you want the Arduino environment with STM32 cpu , you could use Arduino_Core_STM32 boards lib.

Most STM32 have a single byte depth buffer in the UARTs. To read that check the RXNE bit.
To make larger buffers you can query you should make a fifo/ring buffer you fill via interrupts.
