Checkpoint - easy to use parent-child synchronization.
|
|
Checkpoint is based on futexes (man futex). The library allocates a page of
|
shared memory for futexes and the id is an offset to it which gives the user
|
up to page_size/sizeof(uint32_t) checkpoint pairs. Up to INT_MAX processes
|
can sleep on single id and can be woken up by single wake.
