46<H2>Description</H2>
47<P>Executes the function indicated by <SPAN class="argument">pc</SPAN> using a new stack specified by <SPAN class="argument">newsp</SPAN>. When the function returns, the old stack pointer is restored.</P>
48<P>Unlike <a href="OSSwitchFiber.html"><CODE>OSSwitchFiber</CODE></a>, four arguments can be passed to the function specified by <SPAN class="argument">pc</SPAN>. The type of the specified function's arguments does not need to be <CODE>u32</CODE>, as long as it can be passed to registers (such as a pointer). Also, the number of arguments may be less than four.</P>
