Stm32 hal_uart not working

hi i’m using stm32 l496zg-p board in that i took one blink example in that example trying to create uart communication using C file i used HAL_UART_init() function along with transmit function it’s not working

stm32 32 hal_driver function can i use for transmission inside of c++ functions?

and main.cpp file will call uart init function it will take care further process of communication but it’s not working
i used extern “C”
