Another way,

substring (GString *str, int index, int len)
{
 return g_string_new_len (str->str, index, MIN (str->len - index, len));
}

taken from http://bugzilla.gnome.org/show_bug.cgi?id=109286#c2 .


I personally would like that glib provide those small but useful
string functions (like other high level languages do), for example,
glib doesn't provide a simple function to replace strings, like this
one written by Tim in
http://bugzilla.gnome.org/show_bug.cgi?id=65987#c2 ,

gchar *
g_strreplace (const gchar *string,
             const gchar *search,
             const gchar *replacement)


Instead you currently have to use gregex to replace some simple
strings (where no regex are involved).

First of all thanks to everyone who replayed.
The implementation using g_srtndup looks ok.

I was wondering why not to add a so simple example in the official docs (maybe in the g_strndup explanation).
