Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -

What's the point of passing address of pointer to function that needs pointer to pointer ?
16 août 2019, par Guerlando OCsI’m reading an example of ffmpeg decoding and it has the address of a pointer being passed to a function :
static AVBufferRef *hw_device_ctx = NULL;
if ((err = av_hwdevice_ctx_create(&hw_device_ctx, type,
NULL, NULL, 0)) < 0) {What’s the point of passing the address of a pointer as an argument ?
I understand that when we pass the pointer itself, if the pointer has address
0x123456
, then the function is going to be able to modify what’s the object that is in this address. But when I pass the address of a pointer, I’m passing the address of where this pointer number is allocated ?If I understood right, I’m passing the address of the variable that stores
0x123456
? Why the function needs it ?Also, suppose that I want to store
hw_device_ctx
in aunique_ptr
like this :std::unique_ptr<avbufferred> hw_pointer;
</avbufferred>How can I pass it to
av_hwdevice_ctx_create
? Because I get an error when I doav_hwdevice_ctx_create(&hw_pointer.get(),...
It says :
expression must be an lvalue or a function designator

13 août 2013, par Martin Storsjörtpproto : Add an option for writing return packets to the address of the last received packets
If we’ve received packets on the same socket before, the return
packets are sent to that address. If we’ve only received packets
on the other socket, try to guess the source port for the other
one assuming the basic ×1 logic.Signed-off-by : Martin Storsjö <martin@martin.st>
