For clinical, educational, or research teams who need to measure comprehensive listening, speaking, reading, writing, and math skills, the WIAT-III is an individually-administered achievement test for children, adolescents, and adults. See our Guidance on using this assessment remotely. A newer version of the WIAT is now available.

2018年9月2日 · 当进程调用 wait () 时，会暂停目前进程的执行（即阻塞），由 wait () 来自动分析是否当前进程的某个子进程已经退出，如果找到了这样一个已经变成僵尸进程的子进程，wait 就会收集这个子进程的信息，并将其彻底销毁后返回；如果没有找到这样一个子进程，wait 就会一直阻塞在这里，直到出现僵尸进程。 参数 status 保存着子进程退出时的一些状态（包括 task_struct、thread_info及内核栈等）它是一个指向 int 类型的指针；如果不在意子进程的结束状态值，只 …

宏是死的，人是活的，遇到宏不能解决的问题时，自己看看到底问题出现在了哪里（制作力不够技能？ 作业推不满？ 品质不达标？ ）然后打开宏添加上对应的步骤即可。

2022年10月23日 · ff14宏wait.2和wait.3区别目前没有完美解决的办法，只有一个折中的办法，先写好下面三个宏，然后宏1放1号技能栏，宏2放在4号技能栏同样的位置，宏3放在5号技能栏同样位置，试试把，成功了给分哦~ 宏1：精准刺/mi

The wait () function shall suspend execution of the calling thread until status information for one of the terminated child processes of the calling process is available, or until delivery of a signal whose action is either to execute a signal-catching function or to terminate the process.

2016年1月24日 · wait3和wait4函数除了可以获取子进程状态转变信息外，还可以获得子进程的资源使用信息。 pid_t wait3 ( int * status, int option, struct rusage * ru ); pid_t wait4 ( pid_t pid, int * status, int option, struct rusage * ru ); option的可选值有：WNOHANG、WCONTINUED、WUNTRACED。 wait3等待所有的子进程；wait4可以像waitpid一样指定要等待的子进程：pid>0表示子进程ID；pid=0表示当前进程组中的子进程；pid=-1表示等待所有子进程；pid<-1表示进程 …

wait, waitpid — wait for a child process to stop or terminate. #include <sys/wait.h> pid_t wait(int * stat_loc); pid_t waitpid(pid_t pid, int * stat_loc, int options); The wait () and waitpid () functions shall obtain status information. (see Section 2.13, Status Information) pertaining to one of the. caller's child processes.

In other words, wait3 () waits of any child, while wait4 () can be used to select a specific child, or children, on which to wait. See wait (2) for further details. If rusage is not NULL, the struct rusage to which it points will be filled with accounting information about the child. See getrusage (2) for details. As for waitpid (2).

wait3 is a command in Linux that waits for a given child process to complete execution and returns the child’s exit status. It is a synchronous, system call-based command, designed to provide finer control over child process management than the wait command. status: Pointer to an integer variable to store the exit status of the child process.

The wait3 () function allows the calling thread to obtain status information for specified child processes. In order to wait for the status of a terminated child process whose real or saved user ID is different from the calling process's real or effective user ID, your process must have the PROCMGR_AID_WAIT ability enabled.
