                                                                                       explain_sprintf_or_die(3)

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

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

       data    The data, exactly as to be passed to the sprintf(3) system call.

       format  The format, exactly as to be passed to the sprintf(3) system call.

       The explain_sprintf_or_die function is intended to be used in a fashion similar to the following example:
              int result = explain_sprintf_or_die(data, format, ...);

       explain_sprintf_or_die - formatted output conversion and report errors

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

       The explain_sprintf_on_error function always returns the value return by the  wrapped  sprintf(3)  system
       call.
