int ida_get_new_above ( | struct ida * ida, |
| int start, | |
int * id); |
struct ida * idaida handle
int startid to start search at
int * idpointer to the allocated handle
Allocate new ID above or equal to start. It should be called
with any required locks to ensure that concurrent calls to
ida_get_new_above / ida_get_new / ida_remove are not allowed.
Consider using ida_simple_get if you do not have complex locking
requirements.
If memory is required, it will return -EAGAIN, you should unlock
and go back to the ida_pre_get call. If the ida is full, it will
return -ENOSPC. On success, it will return 0.
id returns a value in the range start ... 0x7fffffff.
