Re: Porting ClearSilver

Oh ... with integer I meant 10I 0 and 10U 0.

I have compiled the module again with the options and got:

CSTOKEN_TYPE Class = typedef, Length = 4, Type =
enum with no tag

31-94.3$ 31-111.3 31-146.3 0-897.3
0-906.3

0-1089.1 0-1102.32 0-1948.75
0-2040.72 0-2092.73

I assume that the enum CSTOKEN_TYPE is an integer (signed or unsigned,
but probably signed). Is that right?

Thanx in advance

Also I am standing before the task of creating procedure prototypes

for RPG and am having some difficulties, especially with the data
structures.

typedef struct _neo_err
{
...
/* internal use only */
struct _neo_err *next;
} NEOERR;

Here the structure has a subfield with the type of itself ( struct

_neo_err *next). AFAIK this is not possible in RPG. Is there a
workaround?

RPG doesn't have typed pointers, so you would just define next as a
pointer.

D neoerr1 ds likeds(NEOERR)
D based(pNeoerr1)

pNeoerr1 = address of the first structure;
dow pNeoerr1 <> *null;
--- work with neoerr1 ---
pNeoerr1 = neoerr1.next;
enddo;

typedef enum
{
/* Unary operators */
CS_OP_NONE = (1<<0),
CS_OP_EXISTS = (1<<1),
CS_OP_NOT = (1<<2),
CS_OP_NUM = (1<<3),
...

} CSTOKEN_TYPE;

typedef struct _arg
{
CSTOKEN_TYPE op_type;
char *argexpr;
...
} CSARG;

How would I define the CSTOKEN_TYPE subfield in an RPG data structure?

The actual type of an C enum depends on your compile options (ENUM
parameter) and on the enum values. Compile the C version of the enum
and struct with OPTION(*AGR *XREF) and find out the size and type that C

is using for the enum and subfield. It will be either 1, 2, 4, 8 byte
integer or unsigned, that will map to one of RPG's 3i, 5i,10i, 20i, 3u,
5u, 10u or 20u.
