Hello
Thanks for answer.

No.
Lest's see...
i got function "do_work" with:
1. new Glist init with random data
2. callback definition of button click: button_click(...., GList *list)
let init list poiner = 0xfe
button was clicked!
Here button_click(GList *list)
list in agrs = 0xfe
new data record memory allocation.
!!! g_list_append(data, list) !!!
In my example it returns init list value (0xfe), but should returns
value
of newly created list (0x832c610 in example).
In example:
INIT list prt: 0x830f080 - this is init list, which passed to
button_callback
In button callback:
Created: 0x830f080, arg: 0x830f080 - first ptr is returned list
from
g_list_append(), but it equal to init list. WTF??? HOW?? I need newly created
list here...
And i check added value with g_list_last(). It's equal
0x832c610 and
correct.
So, why g_list_append() dont' return me newly created list???
