CREATEABLXORBINEXPR(3)           ABL FUNCTIONS          CREATEABLXORBINEXPR(3)



NAME
       createablxorbinexpr - creates an 'xor' or 'xnor' operator expression.

>> Included manual page: man1/alc_origin.1alc

SYNOPSIS
       #include "abl101.h"
       chain_list *createablxorbinexpr( Oper, Expr1, Expr2 )
         long        Oper;
         chain_list ∗Expr1;
         chain_list ∗Expr2;

PARAMETERS
       Oper                Operator ABL_XOR or ABL_NXOR.

       Expr1               First expression.

       Expr2               Second expression.

DESCRIPTION
       createablxorbinexpr creates a binary 'xor' or 'xnor' operator
       expression with the 'and', 'or' form.  createablbinexpr simplifies
       eventually the sub-expressions.  The expression pointers Expr1 and
       Expr2 MUSTN'T be used after the call to this function.

RETURN VALUE
       createablxorbinexpr returns a pointer to the new operator expression.

ERRORS
       "ablcreate: bad operator xx !",
              Operator must be ABL_XOR or ABL_NXOR.

EXAMPLE
       #include "abl101.h"
          chain_list ∗ExprA;
          chain_list ∗ExprB;
          chain_list ∗ExprAxorB;
          ExprA = createablatom( "a" );
          ExprB = createablatom( "b" );
          ExprAxorB  = createablxorbinexpr( ABL_XOR, ExprA, ExprB );
          /* displays (a and (not b) or (b and (not a)) */
          viewablexpr( ExprAxorB, ABL_VIEW_VHDL );
