int idr_get_new ( | struct idr * idp, |
| void * ptr, | |
int * id); |
idpidr handle
ptrpointer you want associated with the id
idpointer to the allocated handle
If allocation from IDR's private freelist fails, idr_get_new_above will
return -EAGAIN. The caller should retry the idr_pre_get call to refill
IDR's preallocation and then retry the idr_get_new_above call.
If the idr is full idr_get_new_above will return -ENOSPC.
id returns a value in the range 0 ... 0x7fffffff
