isatty()

fileno

)

Test POSIX fileno if it is a Serial Console/TTY.

• POSIX character I/O functions
  • man page isatty (3).

Parameters

[in]

fileno

POSIX fileno of open file.

Returns

1 if fileno is a serial TTY/Console (uart in avr-libc terms).

0 if POSIX fileno is NOT a Serial TTY.

Todo:

Perhaps we should verify console functions have been added ?
