equalVarExpr(2)

ORIGIN
Cao-vlsi libraries, log package, libablmmm.a

NAME
equalVarExpr - checks that two expressions are syntactically equal

SYNOPSIS
#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 differents, in any other case, 1 is returns. 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);
