NAME

       explain_uname_or_die - get information about current kernel and report errors

SYNOPSIS

       #include <libexplain/uname.h>
       void explain_uname_or_die(struct utsname *data);
       int explain_uname_on_error(struct utsname *data);

DESCRIPTION

       The  explain_uname_or_die function is used to call the uname(2) system call. On failure an
       explanation will be printed to stderr, obtained from the  explain_uname(3)  function,  and
       then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_uname_on_error  function is used to call the uname(2) system call. On failure
       an explanation will be printed to stderr, obtained from the explain_uname(3) function, but
       still returns to the caller.

       data    The data, exactly as to be passed to the uname(2) system call.

RETURN VALUE

       The  explain_uname_or_die  function  only  returns  on  success,  see  uname(2)  for  more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_uname_on_error function  always  returns  the  value  return  by  the  wrapped
       uname(2) system call.

EXAMPLE

       The  explain_uname_or_die  function  is  intended  to  be used in a fashion similar to the
       following example:
              explain_uname_or_die(data);
