<DT><B> Usage </B><DD><P><CODE>char *SLrealloc (char *ptr, unsigned int new_size)</CODE>
<DT><B> Description </B><DD><P>The <CODE>SLrealloc</CODE> uses the <CODE>realloc</CODE> function to resize the
memory block specified by <CODE>ptr</CODE> to the new size <CODE>new_size</CODE>.
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.
