# xcb\_randr\_list\_provider\_properties\_atoms\_length(3)

Part of [xcb\_randr\_list\_provider\_properties(3)](/xcb_randr_list_provider_properties/3.md).

## NAME

xcb\_randr\_list\_provider\_properties -

## SYNOPSIS

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

### Request function

xcb\_randr\_list\_provider\_properties\_cookie\_t **xcb\_randr\_list\_provider\_properties**(xcb\_connection\_t \**conn*, xcb\_randr\_provider\_t *provider*);

### Reply datastructure

```

typedef struct xcb_randr_list_provider_properties_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t num_atoms;
    uint8_t  pad1[22];
} xcb_randr_list_provider_properties_reply_t;
```

### Reply function

xcb\_randr\_list\_provider\_properties\_reply\_t \***xcb\_randr\_list\_provider\_properties\_reply**(xcb\_connection\_t \**conn*, xcb\_randr\_list\_provider\_properties\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);

### Reply accessors

xcb\_atom\_t \***xcb\_randr\_list\_provider\_properties\_atoms**(const xcb\_randr\_list\_provider\_properties\_request\_t \**reply*);

int **xcb\_randr\_list\_provider\_properties\_atoms\_length**(const xcb\_randr\_list\_provider\_properties\_reply\_t \**reply*);

xcb\_generic\_iterator\_t **xcb\_randr\_list\_provider\_properties\_atoms\_end**(const xcb\_randr\_list\_provider\_properties\_reply\_t \**reply*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *provider*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_RANDR\_LIST\_PROVIDER\_PROPERTIES*. 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).

- *num\_atoms*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_randr\_list\_provider\_properties\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_randr\_list\_provider\_properties\_reply*.

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

## ERRORS

This request does never generate any errors.
