## NAME

xcb\_randr\_get\_output\_property -

## SYNOPSIS

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

### Request function

xcb\_randr\_get\_output\_property\_cookie\_t **xcb\_randr\_get\_output\_property**(xcb\_connection\_t \**conn*, xcb\_randr\_output\_t *output*, xcb\_atom\_t *property*, xcb\_atom\_t *type*, uint32\_t *long\_offset*, uint32\_t *long\_length*, uint8\_t *\_delete*, uint8\_t *pending*);

### Reply datastructure

```

typedef struct xcb_randr_get_output_property_reply_t {
    uint8_t    response_type;
    uint8_t    format;
    uint16_t   sequence;

```

### Reply function

xcb\_randr\_get\_output\_property\_reply\_t \***xcb\_randr\_get\_output\_property\_reply**(xcb\_connection\_t \**conn*, xcb\_randr\_get\_output\_property\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);

### Reply accessors

uint8\_t \***xcb\_randr\_get\_output\_property\_data**(const xcb\_randr\_get\_output\_property\_request\_t \**reply*);

int **xcb\_randr\_get\_output\_property\_data\_length**(const xcb\_randr\_get\_output\_property\_reply\_t \**reply*);

xcb\_generic\_iterator\_t **xcb\_randr\_get\_output\_property\_data\_end**(const xcb\_randr\_get\_output\_property\_reply\_t \**reply*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *output*

  TODO: NOT YET DOCUMENTED.

- *property*

  TODO: NOT YET DOCUMENTED.

- *type*

  TODO: NOT YET DOCUMENTED.

- *long\_offset*

  TODO: NOT YET DOCUMENTED.

- *long\_length*

  TODO: NOT YET DOCUMENTED.

- *\_delete*

  TODO: NOT YET DOCUMENTED.

- *pending*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_RANDR\_GET\_OUTPUT\_PROPERTY*. 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).

- *format*

  TODO: NOT YET DOCUMENTED.

- *type*

  TODO: NOT YET DOCUMENTED.

- *bytes\_after*

  TODO: NOT YET DOCUMENTED.

- *num\_items*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_randr\_get\_output\_property\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_randr\_get\_output\_property\_reply*.

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

## ERRORS

This request does never generate any errors.
