[Vala] Convert string to int

[Chriss Kalogeropoulos <iz iznogood gmail com>]

Hi all,

i just started to play with vala and i find it very interesting and
promising project.

How can i validate that the string conversion to int has actually
happened ? It does not throw any exceptions and it seems to use atoi
which returns 0 on failure, which does not say much.

Generally if a method fails how does it handle it ? It throws exceptions
or uses some global error code ? I read in a previous post that vala
only handles glib and friends errors but not normal c library errors
although they are used all over.

Thanks in advance
