CREATEABLXORBINEXPR(3) ABL FUNCTIONS CREATEABLXORBINEXPR(3) NAME createablxorbinexpr - creates an 'xor' or 'xnor' operator expression. 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 ); SEE ALSO abl(1) abl(1) createablatom(3), createabloper(3), createablbinexpr(3), cre- ateablunaryexpr(3), createablnotexpr(3), addablhexpr(3), addablqexpr(3).
