quark_process_lookup —
lookup a quark_process in quark's
cache
#include
<quark.h>
const struct quark_process *
quark_process_lookup(struct
quark_queue *qq, int
pid);
quark_process_lookup looks for the cached process
referenced by pid.
Quark's internal cache keeps processes that exited for a grace time, meaning you can still lookup them for a little while before they're garbage collected. At the time of this writing, this is hardcoded to 4 seconds.
Returns a pointer to the internal process if found. The pointer points to the internal process used by quark, therefore, its contents must NOT be modified, or accessed while quark_queue_get_events(3) is taking place, as this might free the pointed memory.
