This package provides semi-portable access to hardware provided
|
||
|
|
atomic memory operations. These might allow you to write code:
|
||
|
|
|
||
|
|
- That does more interesting things in signal handlers.
|
||
|
|
- Makes more effective use of multiprocessors by allowing you to write
|
||
|
|
clever lock-free code. Note that such code is very difficult to get
|
||
|
|
right, and will unavoidably be less portable than lock-based code. It
|
||
|
|
ia also not always faster than lock-based code. But it may occasionally
|
||
|
|
be a large performance win.
