<DT><U>Function:</U> bool <B>ap_linexpr0_set_list</B> <I>(ap_linexpr0_t* <VAR>e</VAR>, ...)</I>
<DD>This function assign the linear expression <VAR>E</VAR> from a list of
tags of type <CODE>ap_coefftag_t</CODE>, each followed by a number of
arguments as specified in the definition of the tye
<CODE>ap_coefftag_t</CODE>. The list should end with the tag
<CODE>AP_COEFF_END</CODE>.
</P><P>
Return <CODE>true</CODE> in case <CODE>ap_linexpr0_coeffref(e,dim)</CODE>
returns NULL for one of the dimensions involved.

Here is a typical example:
<TABLE><tr><td> </td><td class=example><pre>ap_linexpr0_set_list(e,
AP_COEFF_S_INT, 3, 0,
AP_COEFF_S_FRAC, 3,2, 1,
AP_COEFF_S_DOUBLE, 4.1, 2,
AP_CST_I_DOUBLE, -2.4, 3.6,
AP_END); /* Do not forget the last tatg ! */
</pre></td></tr></table>which transforms an null expression into <CODE>3 x0 + 3/2 x1 + 4.1 x2 + [-2.4,3.6]</CODE>
and is equivalent to:
<TABLE><tr><td> </td><td class=example><pre>ap_linexpr0_set_coeff_scalar_int(e,0, 3);
ap_linexpr0_set_coeff_scalar_frac(e,1, 3,2);
ap_linexpr0_set_coeff_scalar_double(e,2, 4.1);
ap_linexpr0_set_cst_interval_double(e, -2.4, 3.6);
