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);

SEE ALSO

       explain_putw(3)
