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);
