Name

createBinExpr - creates a binary operator expression with an eventual merging of the operators.

Synopsys

#include logmmm.h"
chain_list *createBinExpr(oper,expr1,expr2) short oper;
chain_list *expr1,*expr2;

Parameters

oper
Operator number (#define OR,AN,XOR,NAND,NOR...).
expr1
first expression.
expr2
second expression.

Description

createBinExpr() creates the head of an expression that has got oper as operator and expr1 and expr2 as arguments. If expr1 or expr2 have already oper as operator, oper is merged in the expression that the function returns.

Example

#include mutnnn.h
/* mbk utilities */ #include logmmm.h" chain_list *expr; chain_list *expr1,*expr2;

expr1 = createExpr(OR);
addQExpr(expr1,createAtom("var1"));
addQExpr(expr1,createAtom("var2"));
expr2 = notExpr(createAtom("var3"));
expr = createBinExpr(OR,expr1,expr2);
displayExpr(expr);

/* it will display
(OR var1 var2 (NOT var 3))
*/

freeExpr(expr);
/* don't free expr1 or expr2 ! */

Error

createBinExpr : error - bad operator" The operator number must be included between MIN_OPER and MAX_OPER and must be different from NOT.
