hi
i must be seriously jetlagged :) or i just woke up on the wrong
side of bed today :) i am looking at getting the deviceUniqueID
for a SD card .. and, the code is as follows:
---
#ifdef PLATFORM_SD
UInt32 expMgrVersion;
Err err;
globals->idType = uniqueID;
globals->dataPtr = NULL;
MemSet(globals->data.deviceUniqueID, expCardInfoStringMaxLen+1, 0);
err = FtrGet(sysFileCExpansionMgr, expFtrIDVersion, &expMgrVersion);
if (err == errNone)
{
ExpCardInfoType cardInfo;
UInt16 slotRef;
UInt32 slotIterator;
slotIterator = expIteratorStart;
while (slotIterator != expIteratorStop)
{
err = ExpSlotEnumerate(&slotRef, &slotIterator);
if (err == errNone)
{
// suck the info from the card
err = ExpCardInfo(slotRef, &cardInfo);
if ((err == errNone) && (slotRef != expInvalidSlotRefNum))
{
StrCopy(cardInfo.deviceUniqueIDStr, globals->data.deviceUniqueID);
if (globals->data.deviceUniqueID[0] != '\0')
globals->dataPtr = globals->data.deviceUniqueID;
}
#ifdef DEBUG
else
{
Char str[32];
switch (err)
{
case expErrCardNotPresent:
StrCopy(str, "Card Not Present.");
break;
case expErrInvalidSlotRefNum:
StrCopy(str, "Invalid Slot Reference.");
break;
case expErrSlotDeallocated:
StrCopy(str, "Slot Deallocated.");
break;
default:
StrCopy(str, "invalid slot reference.");
break;
}
FrmCustomAlert(debugAlert, "Unable to read card info", str, NULL);
}
#endif
}
else goto CARD_FIND_EXIT;
}
}
#ifdef DEBUG
else
FrmCustomAlert(debugAlert, "ExpansionMgr not found.", NULL, NULL);
#endif
CARD_FIND_EXIT:
#endif
any enlightenment? :)
