+Name

+
+LIRC_GET_LENGTH - Retrieves the code length in bits.
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, __u32 *length )
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by open().
+
+``request``
+    LIRC_GET_LENGTH
+
+``length``
+    length, in bits
+
+
+Description
+===========
+
+Retrieves the code length in bits (only for ``LIRC-MODE-LIRCCODE``).
+Reads on the device must be done in blocks matching the bit count.
+The bit could should be rounded up so that it matches full bytes.
+
+
+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.
