Yes. It would be great to have such software available for all ILE Languages. At last a real template engine for the System i (without the need to use Java and Velocity, which works ... even from RPG , but is not a good way to go, though Velocity is a great template engine).

I'm quite new to C especially ILE C and am trying to port a software
written in C (with target platform Linux/Unix) to ILE C.

The software uses the lockf() function which is available on other
platforms but not on System i.

The "UNIX C Applications Porting to AS/400 Companion Guide" also points out
that there are problems but gives a function which should be used for

On most (probably all) systems lockf the following declaration:
int lockf(int fildes, int function, off_t size);

But the function from the IBM redbook has:
int lockf(_RFILE *fildes, int function, int size)

Where _RFILE is:

typedef _Packed struct {
char reserved1[16];
volatile void *const *const in_buf;
volatile void *const *const out_buf;
char reserved2[48];
_RIOFB_T riofb;
char reserved3[32];
const unsigned int buf_length;
char reserved4[28];
volatile char *const in_null_map;
volatile char *const out_null_map;
volatile char *const null_key_map;
char reserved5[48];
const int min_length;
short null_map_len;
short null_key_map_len;
char reserved6[8];

What do I have to do to get these two worlds together ?

For those interested: I try to port the template engine ClearSilver ( to ILE C to be able to use it from RPG.

Any ideas?

Thanx in advance
