r.in.poly from stdin

[zarch]

I'm trying to use r.in.poly with the bash pipe, below is reported the code for the North Carolina mapset.

echo """A
    633599.00   225397.00
    641147.00   223978.00
    640818.00   219318.00
    631750.00   222965.00
= 42 stadium""" | r.in.poly input=- output=rtest

but it return:

ERROR: Unable to seek

What is it not able to seek?

G_fseek fix

[rashadkm]

G_fseek is issuing a fatal error instead of non-fatal replacing G_fseek with fseek will solve the problem Find the attached patch

See also #1685 for another G_fseek() ticket with patch.

Thanks for catching this. This was fixed in r38703 for GRASS 7:

• source:grass/trunk/raster/r.in.poly/get_item.c#L59​
• source:grass/trunk/raster/r.in.poly/poly2rast.c#L57​
• source:grass/trunk/raster/r.in.poly/getformat.c#L22​

Closing as fixed.

Now I see that the path is the other way around. So, probably something similar to what was suggested in #1685 should be done. r.in.poly test suite should be extended for the case from this ticket.

It would be good to describe in the manual why fseek works while G_fseek() fails, or fix G_fseek().
