ida_simple_get — get a new id.
int ida_simple_get ( | struct ida * ida, |
| unsigned int start, | |
| unsigned int end, | |
gfp_t gfp_mask); |
struct ida * idathe (initialized) ida.
unsigned int startthe minimum id (inclusive, < 0x8000000)
unsigned int endthe maximum id (exclusive, < 0x8000000 or 0)
gfp_t gfp_maskmemory allocation flags
Allocates an id in the range start <= id < end, or returns -ENOSPC. On memory allocation failure, returns -ENOMEM.
Compared to ida_get_new_above this function does its own locking, and
should be used unless there are special requirements.
Use ida_simple_remove to get rid of an id.
