+LIRC write()
+************
+
+Name
+====
+
+lirc-write - Write to a LIRC device
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. cpp:function:: ssize_t write( int fd, void *buf, size_t count )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+``count``
+
+
+Description
+===========
+
+:ref:`write() <lirc-write>` writes up to ``count`` bytes to the device
+referenced by the file descriptor ``fd`` from the buffer starting at
+``buf``.
+
+The data written to the chardev is a pulse/space sequence of integer
+values. Pulses and spaces are only marked implicitly by their position.
+The data must start and end with a pulse, therefore, the data must
+always include an uneven number of samples. The write function must
+block until the data has been transmitted by the hardware. If more data
+is provided than the hardware can send, the driver returns ``EINVAL``.
+
+
+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. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
