SpatialWare Datablade module 3.0
Hi,
I testing datablade module with C - API for SpatialWare from MapInfo. I
have problem with sample program.
Prgogram core dump in last line at nlst_dump function.
When I debuging this program with gdb and print values
'buf' is
$1 = {st_geometry = 0x583c0ca, st_centroid = {x = 1542465.3467774028,
y = 3375467589.3683138, z = 48421672.351759702}, hg_orientation = {
x = 131072.00048209852, y = -1.7100569603632504e-282,
z = -7.2851991706825489e+37}, hg_envelope = {st_llb_point = {x = 0,
y = 3.2382544625372822e-319, z = 2.7957949023414405e-312},
st_urt_point = {x = -5.8552837933213611e+44, y =
1.1281735991651357e+190,
z = -5.8552764223799439e+44}}, hg_assembled = 1734623525}
but values 'in' is
Cannot access memory at address 0x583c0ca

Used software:
Solaris 2.6
