+VIDIOC_DELETE_BUF - Delete a buffer from a queue
+
+Synopsis
+========
+
+.. c:macro:: VIDIOC_DELETE_BUF
+
+``int ioctl(int fd, VIDIOC_DELETE_BUF, struct v4l2_buffer *argp)``
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open()`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_buffer`.
+
+Description
+===========
+
+Applications can optionally call the :ref:`VIDIOC_DELETE_BUF` ioctl to
+delete a buffer from a queue.
+
+The struct :c:type:`v4l2_buffer` structure is specified in
+:ref:`buffer`.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EBUSY
+    File I/O is in progress.
+
+EINVAL
+    The buffer ``index`` doesn't exist in the queue.
