NAME

       explain_sprintf_or_die - formatted output conversion and report errors

SYNOPSIS

       #include <libexplain/sprintf.h>
       int explain_sprintf_or_die(char *data, const char *format, ...);
       int explain_sprintf_on_error(char *data, const char *format, ...);

DESCRIPTION

       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.

RETURN VALUE

       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.

EXAMPLE

       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, ...);
