Peter,
I have been putting one together as I modify g_smob.c, g_rc.c and
g_register.c
It is in an open office format and is very raw but attached is the
current version. Suggestions on what the API should look like are
allways welcome.
For example, your suggestion
"No. Special case-tastic. If anything, we could make an {s|o}_slot.c and
define slotting API there. Slots _use_ attributes, but aren't necessary
in the attribute API its-self."
Lead me to create a slot structure and an api for slots
//-----------------------------------------------------------------------------
/*
* Peter Clifton suggested the seperation of the slot structure
* the attribute structure
*/
struct st_slot
{
int reference_count;
gchar *name;
GList *entries; // this is a list of SLOT_ENTRY pointers
// SLOT_ENTRY is a private structure of st_slot
ATTRIB *attrib; // this is a reference to the associated ATTRIB
};
and slot entries looks like
//----------------------------------------------------------------
// SLOT_ENTRY Prototypes
struct st_slot_entry
{
int pin_sequence;
gchar *pin_number;
};
SLOT_ENTRY *s_slot_entry_new();
void s_slot_entry_init(SLOT_ENTRY *this_slot_entry, int pin_sequence,
gchar *pin_number);
void s_slot_entry_free(SLOT_ENTRY* this_slot_entry);
SLOT_ENTRY *s_slot_entry_duplicate(SLOT_ENTRY *this_slot_entry);
void s_slot_entry_print(SLOT_ENTRY *this_slot_entry);
Thanks again,
Steve Meier
