NAME

       explain_putw_or_die - output a word (int) and report errors

SYNOPSIS

       #include <libexplain/putw.h>
       void explain_putw_or_die(int value, FILE *fp);
       int explain_putw_on_error(int value, FILE *fp);

DESCRIPTION

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

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

       value   The value, exactly as to be passed to the putw(3) system call.

       fp      The fp, exactly as to be passed to the putw(3) system call.

RETURN VALUE

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

       The explain_putw_on_error function always returns the value return by the wrapped  putw(3)
       system call.

EXAMPLE

       The  explain_putw_or_die  function  is  intended  to  be  used in a fashion similar to the
       following example:
              explain_putw_or_die(value, fp);
