Author: LxmuyuLinks: Wait, waitpidWait1.1 IntroductionThe wait function requires a header file:#include #include Wait function prototype:pid_t Wait (int *status);Once the process has called wait, it immediately blocks itself, and the wait automatically parses if a child process of the current process has exited, and if it finds such a child process that has become a zombie, wait will collect information about the child process and destroy it and retur
.
The prototype of waitpid system calling in the Linux function library is:
# Include
# Include
Pid_t waitpid (pid_t PID, int * status, int options)
In essence, the functions of the system call waitpid and wait are exactly the same, but the waitpid has two more user-controlled parameters PID and options, this provides us with a more flexible way of programming. The following two parameters are described in detail:
PID: It can be seen from the parameter name PID and type pid_t that what is need

PHP uses the PCNTL series functions to do multiple processes to handle a transaction. For example, I need to get 80w data from the database, and then do a series of subsequent processing, this time, with a single process? You can wait until next year today ... So you should use the PCNTL function.
Now let's take a look at an example
