createablbinexpr.3alc - Man Page
creates a binary operator expression.
Synopsis
#include "abl101.h" chain_list ∗createablbinexpr( Oper, Expr1, Expr2 ) long Oper; chain_list ∗Expr1; chain_list ∗Expr2;
Parameters
- Oper
The operator number.
- Expr1
The first expression.
- Expr2
The second expression.
Description
createablbinexpr creates the binary operator expression Expr1 Operator Expr2. If the operator of Expr1 and/or Expr2, and Operator are identicals createablbinexpr merges eventually the sub-expressions. The expression pointers Expr1 and Expr2 MUSTN'T be used after the call to this function.
Return Value
createablbinexpr returns a pointer to the new operator expression.
Errors
"ablcreate: bad operator xx !",
Operator must be defined and must be a binary operator.
Example
#include "abl101.h" chain_list ∗ExprA; chain_list ∗ExprB; chain_list ∗ExprAorB; ExprA = createablatom( "a" ); ExprB = createablatom( "b" ); ExprAorB = createablbinexpr( ABL_OR, ExprA, ExprB );
