Pointers returned from dll function when called from rebol -

i trying ascertain weather can use rebol few programming tasks. have written small program loads external library , calls function returns pointers in of arguments. when run program crashes rebol.exe. hoping can me out. dll function follows:

void xxx swe_utc_time_zone(int32 iyear, int32 imonth, int32 iday,  int32 ihour, int32 imin, double dsec, double dtimezone,  int32 *iyear_utc, int32 *imonth_utc, int32 *iday_utc,  int32 *ihour_utc, int32 *imin_utc, double *dsec_utc) 

and small test program:

rebol [] astrology-lib: load/library %/c/sweph/bin/swedll32.dll swe-utc-time-zone: make routine! [    iyear [integer!]    imonth [integer!]    iday [integer!]    ihour [integer!]    iminute [integer!]    dsec [decimal!]    dtimezone [decimal!]    iyear-utc [char*]    imonth-utc [char*]    iday-utc [char*]    ihour-utc [char*]    iminute-utc [char*]    dsec-utc [char*] ] astrology-lib "_swe_utc_time_zone@60" swe-utc-time-zone 2015 6 20 0 19 0 -4.5 none none none none none none 

the program crashes on last line attempt call function. error message "rebol/view system has stopped working"

you have provide memory @ least same size pointer want call.

so instead of none should use words initialized along line of

iyear-utc: make struct! [     point [integer!] ] none 

maybe these links give more adress, conversions, more conversions
