* @func short | ErrorResBox | This function displays a message box using
* program resource error strings.
*
* @parm HWND | hwnd | Specifies the message box parent window.
*
* @parm HANDLE | hInst | Specifies the instance handle of the module
* that contains the resource strings specified by <p idAppName> and
* <p idErrorStr>. If this value is NULL, the instance handle is
* obtained from <p hwnd> (in which case <p hwnd> may not be NULL).
*
* @parm UINT | flags | Specifies message box types controlling the
* message box appearance. All message box types valid for <f MessageBox> are
* valid.
*
* @parm UINT | idAppName | Specifies the resource ID of a string that
* is to be used as the message box caption.
*
* @parm UINT | idErrorStr | Specifies the resource ID of a error
* message format string. This string is of the style passed to
* <f wsprintf>, containing the standard C argument formatting
* characters. Any procedure parameters following <p idErrorStr> will
* be taken as arguments for this format string.
*
* @parm arguments | [ arguments, ... ] | Specifies additional
* arguments corresponding to the format specification given by
* <p idErrorStr>. All string arguments must be FAR pointers.
*
* @rdesc Returns the result of the call to <f MessageBox>. If an
* error occurs, returns zero.
*
* @comm This is a variable arguments function, the parameters after
* <p idErrorStr> being taken for arguments to the <f printf> format
* string specified by <p idErrorStr>. The string resources specified
* by <p idAppName> and <p idErrorStr> must be loadable using the
* instance handle <p hInst>. If the strings cannot be
* loaded, or <p hwnd> is not valid, the function will fail and return
* zero.
