/*
- * Option bits for the third argument of wait4/waitpid/waitid/wait6.
- * WNOHANG causes the wait to not hang if there are no stopped or
- * terminated processes, rather returning an error indication in this case
- * (pid==0). WSTOPPED indicates that the caller should receive status about
- * untraced children which stop due to signals. If children are stopped and
- * a wait without this option is done, it is as though they were still running,
- * nothing about them is returned. WCONTINUED returns information for children
- * that were continued from job control. WEXITED is the default for
- * wait/wait3/wait4/waitpid (to report children that have exited), but needs
- * to be explicitly specified for waitid/wait6. WNOWAIT returns information
- * about the children without reaping them (changing their status to have
- * been already waited for.
+ * POSIX option bits for the "options" argument of wait{3,4,6} wait{,p}id:
+ *
+ * WNOHANG
+ * Causes the wait to not hang if there are no stopped or terminated
+ * processes, rather returning an error indication in this case (pid==0).

+ * WSTOPPED/WUNTRACED
+ * Indicates that the caller should receive status about untraced
+ * children which stop due to signals. If children are stopped
+ * and a wait without this option is done, it is as though they
+ * were still running, nothing about them is returned.
