+LIRC read()
+***********
+
+Name
+====
+
+lirc-read - Read from a LIRC device
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+ #include <unistd.h>
+
+
+.. cpp:function:: ssize_t read( int fd, void *buf, size_t count )
+
+
+Arguments
+=========
+
+``fd``
+ File descriptor returned by ``open()``.
+
+``buf``
+``count``
+
+
+Description
+===========
+
+:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``. If ``count`` is zero,
+:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
+is greater than ``SSIZE_MAX``, the result is unspecified.
+
+The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and
+what mode has been selected. lircd obtains supported modes and sets the
+active mode via the ioctl interface, detailed at :ref:`lirc_func`.
+The generally preferred mode for receive is
+:ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`, in which packets containing an
+int value describing an IR signal are read from the chardev.
+

+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame. On error, -1 is returned, and the ``errno``
+variable is set appropriately.
