SYNOPSYS¶
#include "abl101.h"
chain_list ∗createabloper( Oper )
long Oper;
PARAMETERS¶
- Oper
- The operator number.
DESCRIPTION¶
createabloper creates the head of an operator expression. Arguments can
be added to this expression with the
addablhexpr and
addablqexpr
functions.
Operator can take the following values ABL_AND, ABL_OR,
ABL_AND, ABL_XOR, ABL_NOT, ABL_NOR, ABL_NAND, ABL_NXOR, ABL_STABLE, ABL_AF,
ABL_AG, ABL_AX, ABL_AU, ABL_EF, ABL_EG, ABL_EX, ABL_EU.
RETURN VALUE¶
createabloper returns a pointer to the new operator expression.
ERRORS¶
"ablcreate: bad operator xx !",
The operator number must be defined.
EXAMPLE¶
#include "abl101.h"
chain_list ∗Expr;
Expr = createabloper( ABL_OR );
addablhexpr( Expr, createablatom( "a" ) );
addablhexpr( Expr, createablatom( "b" ) );
/* displays (a or b) */
viewablexpr( Expr, ABL_VIEW_VHDL );
