## Function Documentation

## xcb_dri3_buffer_from_pixmap()

xcb_dri3_buffer_from_pixmap_cookie_t xcb_dri3_buffer_from_pixmap | ( | xcb_connection_t * | c,
|  | xcb_pixmap_t | pixmap )

Parameters

  c | The connection

Returns
  A cookie

Delivers a request to the X server.

References XCB_DRI3_BUFFER_FROM_PIXMAP.

## xcb_dri3_buffer_from_pixmap_reply()

xcb_dri3_buffer_from_pixmap_reply_t * xcb_dri3_buffer_from_pixmap_reply | ( | xcb_connection_t * | c,
|  | xcb_dri3_buffer_from_pixmap_cookie_t | cookie,
|  | xcb_generic_error_t ** | e )

Return the reply

Parameters

  c | The connection
  cookie | The cookie
  e | The xcb_generic_error_t supplied

Returns the reply of the request asked by

The parameter `e` supplied to this function must be NULL if xcb_dri3_buffer_from_pixmap_unchecked(). is used. Otherwise, it stores the error if any.

The returned value must be freed by the caller using free().

## xcb_dri3_buffer_from_pixmap_reply_fds()

int * xcb_dri3_buffer_from_pixmap_reply_fds | ( | xcb_connection_t * | c,

Return the reply fds

Parameters

  c | The connection
  reply | The reply

Returns a pointer to the array of reply fds of the reply.

The returned value points into the reply and must not be free(). The fds are not managed by xcb. You must close() them before freeing the reply.

## xcb_dri3_buffer_from_pixmap_unchecked()

xcb_dri3_buffer_from_pixmap_cookie_t xcb_dri3_buffer_from_pixmap_unchecked | ( | xcb_connection_t * | c,

Parameters

  c | The connection

Returns
