If <CODE>f</CODE> is <CODE>NULL</CODE> the default handler will get installed. <DT><B> Example </B><DD><P>The default interrupt handler on a Unix system is: <BLOCKQUOTE><CODE> <PRE> static void default_sigint (int sig) { SLKeyBoard_Quit = 1; if (SLang_Ignore_User_Abort == 0) SLang_Error = SL_USER_BREAK; SLsignal_intr (SIGINT, default_sigint); } </PRE> </CODE></BLOCKQUOTE> <DT><B> Notes </B><DD><P>For Unix programmers, the name of this function may appear misleading since it is associated with <CODE>SIGINT</CODE> and not <CODE>SIGABRT</CODE>. The origin of the name stems from the original intent of the function: to allow the user to abort the running of a <B>S-lang</B> interpreter function. <DT><B> See Also </B><DD><P><CODE>SLang_init_tty, SLsignal_intr</CODE> </DL> <P> <P> <P> <HR> <A HREF="cref-118.html">Next</A> <A HREF="cref-116.html">Previous</A> <A HREF="cref.html#toc117">Contents</A> </BODY> </HTML>
