[GRASS-dev] Some simple questions about coding style.

[Maris Nartiss]

Hi all,
I was looking at g.copy source and now I have some simple questions:
1) Is it safe to pass int to G_calloc(), as it expects size_t?
2) Is it safe to G_malloc() fixed amount for parser's option
description? (opt->description)
3) Why G_warning isn't a viod function? It always returns 0 and none
of GRASS modules performs check for it's return value.

Thanks for answers to GRASS C guru's.
Maris.
