12 | * The fields of BASEOP are:

13 | * op_next Pointer to next ppcode to execute after this one.

14 | * (Top level pre-grafted op points to first op,
|
---|
15 | * but this is replaced when op is grafted in, when
|
---|
16 | * this op will point to the real next op, and the new
|
---|
17 | * parent takes over role of remembering starting op.)
|
---|
18 | * op_ppaddr Pointer to current ppcode's function.
|
---|
19 | * op_type The type of the operation.
|
---|
20 | * op_flags Flags common to all operations. See OPf_* below.
|
---|
21 | * op_private Flags peculiar to a particular operation (BUT,
|
---|
22 | * by default, set to the number of children until
|
---|
23 | * the operation is privatized by a check routine,
|
---|
24 | * which may or may not check number of children).
