explain_tcgetattr_or_die - get terminal parameters and report errors
#include <libexplain/tcgetattr.h>
void explain_tcgetattr_or_die(int fildes, struct termios *data);
int explain_tcgetattr_on_error(int fildes, struct termios *data);
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.
The explain_tcgetattr_or_die function only returns on success, see tcgetattr(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_tcgetattr_on_error function always returns the value return by the wrapped tcgetattr(3) system call.
The explain_tcgetattr_or_die function is intended to be used in a fashion similar to the following example:
explain_tcgetattr_or_die(fildes, data);
