Re: convert from alpha to int

[Yann Leydier <yann leydier info>]

Hi,

I don't know if Glib has functions to perform such a check, but standard 
C does:
http://www.cplusplus.com/reference/clibrary/cctype/

If you know that the string's digital value cannot be 0, then you can 
also check a non-null return to atoi or atol (in cstdlib).
