Hi,
I want to build an IDL wrapper for a C function that returns a struct.
This struct contains several arrays and other data. I'm returning an
anonymous structure but for "big" arrays (with "big" I mean about 7000
elements). I get at run-time the error "Array has too many elements".
This is the essential code (for just one array):
static IDL_MEMINT node_dims[IDL_MAX_ARRAY_DIM];
static IDL_STRUCT_TAG_DEF NodeStats_tags[] = {
{ "NODEVOXELS_COUNT", 0, (void *) IDL_TYP_UINT},
{ "NODEVOXELS_WIDTH", node_dims, (void *) IDL_TYP_DOUBLE},
{ 0 }
};
IDL_VPTR p3d_idlFoo(int argc, IDL_VPTR argv[], char* argk) {
...
struct NodeStats stats;
IDL_LONG tmp_dims[IDL_MAX_ARRAY_DIM];
IDL_MEMINT offset;
double* d_tmp_ptr;
unsigned short* us_tmp_ptr;
char* s_data;
...
Skel_tags_node_dims[0] = 1;
Skel_tags_node_dims[1] = (IDL_MEMINT) stats.Node_Counter;
s = IDL_MakeStruct(NULL, SkelStats2_tags);
tmp_dims[0] = 1;
s_data = (char *) IDL_MakeTempStruct(s, 1, tmp_dims, &idl_out_struct,
0);
offset = IDL_StructTagInfoByName(s, "NODEVOXELS_COUNT",
IDL_MSG_LONGJMP, NULL);
us_tmp_ptr = (unsigned short *) (s_data + offset);
*(us_tmp_ptr++) = stats.Node_Counter;
offset = IDL_StructTagInfoByName(s, "NODEVOXELS_WIDTH",
IDL_MSG_LONGJMP, NULL);
d_tmp_ptr = (double *) (s_data + offset);
for (i = 0; i < stats.Node_Counter; i++)
*(d_tmp_ptr++) = stats.Node_Width[i];
...
}
What am I doing wrong? Thanks in advance for any help...
Franz
