NAME

6       explain_ioctl_or_die - control device and report errors
7

SYNOPSIS

9       #include <libexplain/ioctl.h>
10       int explain_ioctl_or_die(int fildes, int request, void *data);
11

DESCRIPTION

13       The  explain_ioctl_or_die  function is used to call the ioctl(2) system
14       call.  On failure an explanation will be printed  to  stderr,  obtained
15       from  explain_ioctl(3),  and  then  the  process  terminates by calling
16       exit(EXIT_FAILURE).
17
18       This function is intended to be used in a fashion similar to  the  fol‐
19       lowing example:
20              int result = explain_ioctl_or_die(fildes, request, data);
21
22       fildes  The  fildes,  exactly  as  to  be passed to the ioctl(2) system
23               call.
24
25       request The request, exactly as to be passed  to  the  ioctl(2)  system
26               call.
27
28       data    The data, exactly as to be passed to the ioctl(2) system call.
29
30       Returns:
31               This  function  only  returns on success, see ioctl(2) for more
32               information.  On failure, prints an explanation and exit()s.
