Hi all,
Im trying to hyperslab str_tst of type NC_STRING in the netcdf4 file below:

With stride=1,
I allocate some space using:
char **sngp;
sngp=(char**)nco_calloc(var->sz,sizeof(char*));

Then call:
(void)nc_get_vara_string(nc_id,var->id,var->srt,var->cnt,sngp);

The function then fills sng[0] ...sng[var->sz-1] with strings


With stride >1 I call
(void)nc_get_vars_string(nc_id,var->id,var->srt,var->cnt,var->srd,sngp);

What I get returned  is

sng[0]= last element of the hyperslab and

sng[1]...sng[var->sz-1]  ==NULL


Not sure what is happening here ????????
