NAME

6       explain_tcsetattr_or_die - set terminal attributes and report errors
7

SYNOPSIS

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

DESCRIPTION

16       The  explain_tcsetattr_or_die function is used to call the tcsetattr(3)
17       system call. On failure an  explanation  will  be  printed  to  stderr,
18       obtained  from  the explain_tcsetattr(3) function, and then the process
19       terminates by calling exit(EXIT_FAILURE).
20
21       The explain_tcsetattr_on_error function  is  used  to  call  the  tcse‐
22       tattr(3)  system  call.  On  failure  an explanation will be printed to
23       stderr, obtained from  the  explain_tcsetattr(3)  function,  but  still
24       returns to the caller.
25
26       fildes  The  fildes, exactly as to be passed to the tcsetattr(3) system
27               call.
28
29       options The options, exactly as to be passed to the tcsetattr(3) system
30               call.
31
32       data    The  data,  exactly  as to be passed to the tcsetattr(3) system
33               call.
34

RETURN VALUE

36       The explain_tcsetattr_or_die function  only  returns  on  success,  see
37       tcsetattr(3)  for  more  information. On failure, prints an explanation
38       and exits, it does not return.
39
40       The explain_tcsetattr_on_error function always returns the value return
41       by the wrapped tcsetattr(3) system call.
42

EXAMPLE

44       The explain_tcsetattr_or_die function is intended to be used in a fash‐
45       ion similar to the following example:
46              explain_tcsetattr_or_die(fildes, options, data);
