NAME

mapabloperexpr - applies a function to all operands.

See the file buster/alliance/alc_origin.1.en.gz.

SYNOPSYS

#include "abl101.h"
chain_list ∗mapabloperexpr( Function, Oper, Expr )


  chain_list ∗ (∗Function)();


  long       Oper;


  chain_list ∗Expr;

PARAMETERS

Function

Function name to apply to all operands.

Oper

Operator number.

Expr

Expression to scan.

DESCRIPTION

mapabloperexpr applies Function to all operands of Expr. mapabloperexpr creates a head of an operator expression having Oper as operator and adds the arguments calculated by applying Function to each arguments of Expr. Function must return an expression and must have a unique expression as argument.

RETURN VALUE

mapabloperexpr returns a new expression by applying Function to all the arguments of the operator expression Expr.

EXAMPLE

#include "abl101.h"


   chain_list ∗MapFunction( MapExpr )


      chain_list ∗MapExpr;


   {


     return( createablnotexpr( dupablexpr( MapExpr ) ) );


   }


   chain_list ∗Expr;


   chain_list ∗Expr1;


   Expr = createablbinexpr( ABL_NOR,


                            createablatom( "a" ),


                            createablatom( "b" ) );


   Expr1 = mapabloperexpr( MapFunction, ABL_AND, Expr );


   /* displays ((not a) and (not b))  */


   viewablexpr( Expr1, ABL_VIEW_VHDL );
