<P>
An abstraction for a native function pointer. An instance of
<code>Function</code> represents a pointer to some native function.
<A HREF="../../../com/sun/jna/Function.html#invoke(java.lang.Class, java.lang.Object[], java.util.Map)"><CODE>invoke(Class,Object[],Map)</CODE></A> is the primary means to call
the function. <p/>
<a name=callflags></a>
Function call behavior may be modified by passing one of the following call
flags:
<ul>
<li><A HREF="../../../com/sun/jna/Function.html#C_CONVENTION"><CODE>C_CONVENTION</CODE></A> Use C calling convention (default)
<li><A HREF="../../../com/sun/jna/Function.html#ALT_CONVENTION"><CODE>ALT_CONVENTION</CODE></A> Use alternate calling convention (e.g. stdcall)
<li><A HREF="../../../com/sun/jna/Function.html#THROW_LAST_ERROR"><CODE>THROW_LAST_ERROR</CODE></A> Throw a <A HREF="../../../com/sun/jna/LastErrorException.html" title="class in com.sun.jna"><CODE>LastErrorException</CODE></A> if
the native function sets the system error to a non-zero value (errno or
GetLastError). Setting this flag will cause the system error to be cleared
prior to native function invocation.
