There is definitively something wrong in owfs-tcl in 2.6
The path returned always contains "," instead of white space " ". Also the
result always comes back with nothing when it's at the end of the tree.

The problem is in Fowq_output_offset_and_size(). When I looked at the
variables, OWQ_size and OWQ_length didn't contain correct values.
DEBUG: OWQ_size=0 OWQ_length=-1028883844 length=12 copy_length=12
After this, copy_length is set to 0 since OWQ_size == 0.
if ( copy_length > OWQ_size(owq) ) copy_length = OWQ_size(owq) ;
This results into a 0 copied bytes to the output-buffer.
I tried to just comment away this if-statement, and then it worked good…
I'm not sure if this is correct though… OWQ_size should be set to some
bigger value in some other place I guess.

Sounds like a bug in owcapi -- I'll check.

Hi there,
my last posting I assumed this to be a bug of owtcl, but its not!
Presumably I have just got some misunderstanding of the API.
Anyway, this did work with some older Version of owfs!
So, whats wrong with this piece of code:
--cut--
int main() {
char *s;
size_t n;
if(OW_init("localhost:55555") !=0) exit(1);;
OW_get("/10.B963D4000800/type",&s,&n);
printf("%d\n",n);
if (n >0) printf("%s\n",s);
OW_finish();
exit(EXIT_SUCCESS);
}
--cut--
BTW, it works just fine, when I replace "/10.B963D4000800/type" by
"/10.B963D4000800" only.
