DESCRIPTION
The explain_tcgetattr_or_die function is used to call the tcgetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcgetattr(3) function, and then the process terminates by calling exit(EXIT_FAILURE).The explain_tcgetattr_on_error function is used to call the tcgetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcgetattr(3) function, but still returns to the caller.
- fildes
- The fildes, exactly as to be passed to the tcgetattr(3) system call.
- data
- The data, exactly as to be passed to the tcgetattr(3) system call.
