-
-lirc-write - Write to a LIRC device
-
-
-Synopsis
-========
-
-.. code-block:: c
-
- #include <unistd.h>
-
-
-.. c:function:: ssize_t write( int fd, void *buf, size_t count )
- :name: lirc-write
-
-Arguments
-=========
-
-``fd``
- File descriptor returned by ``open()``.
-
-``buf``
- Buffer with data to be written
-
-``count``
- Number of bytes at the buffer
-
-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 exact format of the data depends on what mode a driver uses, use
-:ref:`lirc_get_features` to get the supported mode.
-
-When in :ref:`LIRC_MODE_PULSE <lirc-mode-PULSE>` mode, 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.
