xcb\_dbe\_deallocate\_back\_buffer(3) XCB Requests xcb\_dbe\_deallocate\_back\_buffer(3)

# [NAME](#NAME)

xcb\_dbe\_deallocate\_back\_buffer - Deallocates a back buffer

# [SYNOPSIS](#SYNOPSIS)

**#include <xcb/dbe.h>**

## [Request function](#Request_function)

xcb\_void\_cookie\_t **xcb\_dbe\_deallocate\_back\_buffer**(xcb\_connection\_t \**conn*, xcb\_dbe\_back\_buffer\_t *buffer*);

# [REQUEST ARGUMENTS](#REQUEST_ARGUMENTS)

[*conn*](#conn)

The XCB connection to X11.

[*buffer*](#buffer)

The back buffer to deallocate.

# [DESCRIPTION](#DESCRIPTION)

Deallocates the given *buffer*. If *buffer* is an invalid id, a *BadBuffer* error is returned. Because a window may have allocated multiple back buffer ids, the back buffer itself is not deleted until all these ids are deallocated by this call.

# [RETURN VALUE](#RETURN_VALUE)

Returns an *xcb\_void\_cookie\_t*. Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with *xcb\_request\_check* instead, use *xcb\_dbe\_deallocate\_back\_buffer\_checked*. See [**xcb-requests(3)**](/man/os/libxcb/xcb-requests.3) for details.

# [ERRORS](#ERRORS)

This request does never generate any errors.
