GPtrArray has no insert?

[Martin Kalbfuß]

Hi,

I make a library to handle group of bitmaps for the allegro lib. The
allegro bitmap type is a pointer type.

So a GPtrArray would be the right choice. But I can't see any insertion
function like the GArray has. Is such a function not present or is it
simply not documented?

And what happens when I try to access a non existent element with an out
of range index? The documentation says nothing about this?

Thanks,
Martin

No one knows?

Especially the behavior on an out of range index would be interesting. I
would like to know if I have to implement a check myself.

Thanks

Hi,

there is no g_array_insert_val() equivalent for GPtrArray, you must
implement it by yourself. If you just want to write data, access directy
the pdata field or use g_ptr_array_index().

If you access out of bounds items you get the same results you encounter
with any array: plain garbage if you are reading and a segmentation
fault if you are writing (and lucky).

Ciao.
