Returning user defined data types

[mayank gupta]

Is there any way to return user defined data types (like structures) with user defined functions in CLIPS.

Returning unknown data types supports only CLIPS data types. Or am I missing something?

Hi Mayank,

I think you missed something: a - external address.
Allows you to return (void *) pointers.

/* Copy from extnfunc.h. CLIPS Version 6.24 07/01/05 */
/* Return types are: */
/* a - external address */
/* b - boolean integer (converted to symbol) */
/* c - character (converted to symbol) */
/* d - double precision float */
/* f - single precision float (converted to double) */
/* g - long long integer */
/* i - integer (converted to long long integer) */
/* j - unknown (symbol, string, */
/* or instance name by convention) */
/* k - unknown (symbol or string by convention) */
/* l - long integer (converted to long long integer) */
/* m - unknown (multifield by convention) */
/* n - unknown (integer or float by convention) */
/* o - instance name */
/* s - string */
/* u - unknown */
/* v - void */
/* w - symbol */
/* x - instance address */
