cru_killed - poll the killed state of a graph transformation job
#include <cru/cru.h>
int cru_killed (void)
When called from within any user-written callback function such as an operator or predicate invoked by a cru library function, this function tests whether the job that called the callback function has been killed by cru_kill since the callback function was called. The relevant job is determined automatically provided that cru_killed runs in the same thread as the callback function.
If the job is found to be killed, this function returns a non-zero value. If the job has not been killed or if this function is called outside the thread context of a callback function, it returns zero.
none
Ordinarily this function is not needed because no special action is required in user code to make a killed job terminate early. Using this function is appropriate only when immediate responses to killing events are important and callback functions are long-running. Because cru_kill does not pre-empt user-written code, the callback function should be designed to poll cru_killed and behave accordingly.
Killable operations compatible with this function include cru_built, cru_composed, cru_crossed, cru_fabricated, cru_filtered, cru_induced, cru_mapreduced, cru_merged, cru_mutated, cru_partition_of, cru_postponed, cru_split, and cru_stretched.
