Depends on what screen you're using.

Assuming you're using an ANSI terminal, writing such functions
is pretty simple:

void clearScreen(void)
  {    
    printf("\033[2J")
  }

void clearToEOL(void)
  {
    printf("\033[K")  
  }  
  
void moveCursor(int row, int col)
  {
    printf("\033[%d;%dH",row, col)
  }  

and so on.
