Name

equalVarExpr - checks that two expressions are syntactically equal

Synopsys

#include logmmm.h"
int equalVarExpr(expr1,expr2)
chain_list *expr1,*expr2;

Parameters

expr1
first expression
expr1
second expression

Description

equalVarExpr() compares its arguments and returns 0 if expr1 and expr2 are syntactically different, in any other case, 1 is returned. Contrary to the equalExpr() function, atomic expressions aren't compared.

Example

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

/* Let's suppose that
expr1 = (OR (AND a b) (XOR c d)) expr1 = (OR (AND f b) (XOR a t)) */
printf("%d",equalVarExpr(expr1,expr2));
/* it will display
1
*/
freeExpr(expr2);
expr2 = createExpr(OR);
addQExpr(expr2,createAtom("b"));
addQExpr(expr2,createAtom("a"));
addQExpr(expr2,createAtom("c"));
printf("%d",equalVarExpr(expr1,expr2));
/* it will display
0
*/
freeExpr(expr1); freeExpr(expr2);
