If <CODE>ptr</CODE> is <CODE>NULL</CODE>, the function call is equivalent to <CODE>SLmalloc(new_size)</CODE>. Similarly, if <CODE>new_size</CODE> is zero, the function call is equivalent to <CODE>SLfree(ptr)</CODE>. <P>If the function fails, or if <CODE>new_size</CODE> is zero, <CODE>NULL</CODE> is returned. Otherwise a pointer is returned to the (possibly moved) new block of memory. <DT><B> See Also </B><DD><P><CODE>SLfree, SLmalloc, SLcalloc</CODE> </DL> <P> <P> <P> <HR> <A HREF="cref-98.html">Next</A> <A HREF="cref-96.html">Previous</A> <A HREF="cref.html#toc97">Contents</A> </BODY> </HTML>
