# xcb\_xvmc\_create\_subpicture(3)

## NAME

xcb\_xvmc\_create\_subpicture -

## SYNOPSIS

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

### Request function

xcb\_xvmc\_create\_subpicture\_cookie\_t **xcb\_xvmc\_create\_subpicture**(xcb\_connection\_t \**conn*, xcb\_xvmc\_subpicture\_t *subpicture\_id*, xcb\_xvmc\_context\_t *context*, uint32\_t *xvimage\_id*, uint16\_t *width*, uint16\_t *height*);

### Reply datastructure

```

typedef struct xcb_xvmc_create_subpicture_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;

```

### Reply function

xcb\_xvmc\_create\_subpicture\_reply\_t \***xcb\_xvmc\_create\_subpicture\_reply**(xcb\_connection\_t \**conn*, xcb\_xvmc\_create\_subpicture\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);

### Reply accessors

uint32\_t \***xcb\_xvmc\_create\_subpicture\_priv\_data**(const xcb\_xvmc\_create\_subpicture\_request\_t \**reply*);

int **xcb\_xvmc\_create\_subpicture\_priv\_data\_length**(const xcb\_xvmc\_create\_subpicture\_reply\_t \**reply*);

xcb\_generic\_iterator\_t **xcb\_xvmc\_create\_subpicture\_priv\_data\_end**(const xcb\_xvmc\_create\_subpicture\_reply\_t \**reply*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *subpicture\_id*

  TODO: NOT YET DOCUMENTED.

- *context*

  TODO: NOT YET DOCUMENTED.

- *xvimage\_id*

  TODO: NOT YET DOCUMENTED.

- *width*

  TODO: NOT YET DOCUMENTED.

- *height*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_XVMC\_CREATE\_SUBPICTURE*. 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).

- *width\_actual*

  TODO: NOT YET DOCUMENTED.

- *height\_actual*

  TODO: NOT YET DOCUMENTED.

- *num\_palette\_entries*

  TODO: NOT YET DOCUMENTED.

- *entry\_bytes*

  TODO: NOT YET DOCUMENTED.

- *component\_order*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_xvmc\_create\_subpicture\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_xvmc\_create\_subpicture\_reply*.

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

## ERRORS

This request does never generate any errors.
