how to use getch() ; function in arduino programming as in c ( in conio.h ) is there any header file for getch (); ?

2 
uint8_t getch()
{
  while( !Serial.available());
  return (uint8_t)Serial.read();
}

?

3 
uint8_t getch()
{
  while( !Serial.available());
  return (uint8_t)Serial.read();
}

getch() returns an int (16 bit) not a byte/char. But as Serial can't do EOF. Go on then.

getch() returns an int (16 bit) not a byte/char.

Hence the (completely safe) cast.

But, I just double-checked the prototype for getch, and it returns an "int" anyway.

"getch" is a bit of a mongrel - it can even be a macro.

I don't see any advantage in wrapping Serial.available() and Serial.read() into a getch() function.

There are many situations in which a simple Serial.read() is a poor solution and a more comprehensive system of gathering Serial data is advisable.

Hiding these potential problems in a wrapper that just adds extra code without adding value does not make any sense.
