c - 我怎样才能看到从 child 那里收到的信号名称？

Question

例如:

if (WIFEXITED(status)) {
              printf("Im child, finish with status=%d\n", WEXITSTATUS(status));

是否可以使用信号名称而不是数字？

Answer 1

仅供引用

WIFEXITED(status)
Description:
 Returns True if status was returned for a child that terminated normally. In this case, we can
 execute WEXITSTATUS(status) to fetch the value that the child passed to exit, _exit,or _Exit.
