And now for a specific answer, you can try the following:
// Return true if the database is in a read-only heap (ROM).
Boolean DmDatabaseIsROM ( UInt16 card, LocalID lid ) {
void *gid;
unsigned short heapid;
// The following may be a fairly good indicator, but we need proof.
gid = MemLocalIDToGlobal(lid, card);
if ( MemLocalIDKind(lid) == memIDHandle )
heapid = MemHandleHeapID(gid);
else
heapid = MemPtrHeapID(gid);
// Check to see if the heap the DB is stored in is read only.
// Read-only heaps are a good identifier of ROM.
// And yes, I'd treat Handspring Visor Springboard Flash as ROM.
if ( MemHeapFlags(heapid) & 0x0001 ) /* memHeapFlagReadOnly */
return true;
else
return false;
}
If there are any errors in the above code, I would apprecaite comments.
