|
||
|
|
* @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.
