## SYNOPSIS

**#include \<xcb/dri2.h\>**

### Request function

xcb\_dri2\_wait\_sbc\_cookie\_t **xcb\_dri2\_wait\_sbc**(xcb\_connection\_t \**conn*, xcb\_drawable\_t *drawable*, uint32\_t *target\_sbc\_hi*, uint32\_t *target\_sbc\_lo*);

### Reply datastructure

```

typedef struct xcb_dri2_wait_sbc_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint32_t ust_hi;
    uint32_t ust_lo;
    uint32_t msc_hi;
    uint32_t msc_lo;
    uint32_t sbc_hi;
    uint32_t sbc_lo;
} xcb_dri2_wait_sbc_reply_t;
```

### Reply function

xcb\_dri2\_wait\_sbc\_reply\_t \***xcb\_dri2\_wait\_sbc\_reply**(xcb\_connection\_t \**conn*, xcb\_dri2\_wait\_sbc\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);\

## REQUEST ARGUMENTS

- *conn*

- *target\_sbc\_lo*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_DRI2\_WAIT\_SBC*. This field is also present in the *xcb\_generic\_reply\_t* and can be used to tell replies apart from each other.

- *sequence*

  The sequence number of the last request processed by the X11 server.

- *length*

  The length of the reply, in words (a word is 4 bytes).

- *ust\_hi*

  TODO: NOT YET DOCUMENTED.

- *ust\_lo*

  TODO: NOT YET DOCUMENTED.

- *msc\_hi*

  TODO: NOT YET DOCUMENTED.

- *msc\_lo*

  TODO: NOT YET DOCUMENTED.

- *sbc\_hi*

  TODO: NOT YET DOCUMENTED.

- *sbc\_lo*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_dri2\_wait\_sbc\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_dri2\_wait\_sbc\_reply*.

If you want to handle errors in the event loop instead, use *xcb\_dri2\_wait\_sbc\_unchecked*. See **[xcb-requests(3)](/xcb-requests/3.md)** for details.

## ERRORS

This request does never generate any errors.
