explain_tcsetattr_or_die(3)

NAME

explain_tcsetattr_or_die - set terminal attributes and report errors

SYNOPSIS

#include <libexplain/tcsetattr.h>
void  explain_tcsetattr_or_die(int  fildes,  int  options, const struct
termios *data);
int explain_tcsetattr_on_error(int fildes, int  options,  const  struct
termios *data);

DESCRIPTION

The explain_tcsetattr_or_die function is used to call the tcsetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsetattr(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_tcsetattr_on_error function is used to call the tcsetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsetattr(3) function, but still returns to the caller.

fildes The fildes, exactly as to be passed to the tcsetattr(3) system

call.

options The options, exactly as to be passed to the tcsetattr(3) system

call.

data The data, exactly as to be passed to the tcsetattr(3) system

call.

RETURN VALUE

The explain_tcsetattr_or_die function only returns on success, see tcsetattr(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_tcsetattr_on_error function always returns the value return by the wrapped tcsetattr(3) system call.

EXAMPLE

The explain_tcsetattr_or_die function is intended to be used in a fashion similar to the following example:

explain_tcsetattr_or_die(fildes, options, data);
