50 With the :ref:`select() <func-select>` function applications can suspend
56 :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. When buffers are already in
59 On success :ref:`select() <func-select>` returns the total number of bits set in
63 :ref:`VIDIOC_QBUF` or
64 :ref:`VIDIOC_STREAMON` yet the :ref:`select() <func-select>`
66 or ``writefds``, but subsequent :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
69 When use of the :ref:`read() <func-read>` function has been negotiated and the
70 driver does not capture yet, the :ref:`select() <func-select>` function starts
71 capturing. When that fails, :ref:`select() <func-select>` returns successful and
72 a subsequent :ref:`read() <func-read>` call, which also attempts to start
75 data is already available the :ref:`select() <func-select>` function returns
78 When use of the :ref:`write() <func-write>` function has been negotiated the
79 :ref:`select() <func-select>` function just waits until the driver is ready for a
80 non-blocking :ref:`write() <func-write>` call.
82 All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
83 function or streaming I/O must also support the :ref:`select() <func-select>`
86 For more details see the :ref:`select() <func-select>` manual page.
92 On success, :ref:`select() <func-select>` returns the number of descriptors
118 The Linux kernel implements :ref:`select() <func-select>` like the
119 :ref:`poll() <func-poll>` function, but :ref:`select() <func-select>` cannot
