This assumes that the innermost stack frame is selected; setting <CODE>$sp</CODE> is not allowed when other stack frames are selected. To pop entire frames off the stack, regardless of machine architecture, use <CODE>return</CODE>; see section <A HREF="gdb_12.html#SEC106">Returning from a function</A>. <H3><A NAME="FOOT3" HREF="gdb_10.html#DOCF3">(3)</A></H3> <P>If a procedure call is used for instance in an expression, then this procedure is called with all its side effects. This can lead to confusing results if used carelessly. <H3><A NAME="FOOT4" HREF="gdb_14.html#DOCF4">(4)</A></H3> <P>If you choose a port number that conflicts with another service, <CODE>gdbserver</CODE> prints an error message and exits. <H3><A NAME="FOOT5" HREF="gdb_19.html#DOCF5">(5)</A></H3> <P>In <TT>`gdb-19990707/gdb/refcard.ps'</TT> of the version 19990707 release. <H3><A NAME="FOOT6" HREF="gdb_20.html#DOCF6">(6)</A></H3> <P>If you have a more recent version of GDB than 19990707, look at the <TT>`README'</TT> file in the sources; we may have improved the installation procedures since publishing this manual. <P><HR><P> This document was generated on 23 November 1999 using the <A HREF="http://wwwcn.cern.ch/dci/texi2html/">texi2html</A> translator version 1.51.</P> </BODY> </HTML>
