<refsect1 id='description'><title>DESCRIPTION</title>

<para><emphasis remap='B'>libgpsmm and libQgpsmm</emphasis> are mere wrappers over
	<emphasis remap='B'>libgps</emphasis>. The important difference between the libraries is that libgpsmm is targeted at C++ applications and contained in <emphasis remap='B'>libgps</emphasis>, while libQgpsmm is platform independent by using QTcpSocket to connect to <emphasis remap='B'>gpsd</emphasis> and shipped as an additional library due to the necessary linking to QT.
Method names are the same as
the analogue C functions. For a detailed description of the functions
please read
<citerefentry><refentrytitle>libgps</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
<function>open()</function> must be called after class constructor and before any other method
(<function>open()</function> is not inside the constructor since it may fail, however constructors have no return value).
The analogue of the C function <function>gps_close()</function> is in the destructor.</para>
