(PHP 4>= 4.1.0, PHP 5)pcntl_waitpid -- Waits on or returns the status of a forked child
Description
int pcntl_waitpid (int pid, int &status [, int options])
The pcntl_waitpid() function suspends execution of the current process until a child as specified by the pid argument has exited, or until a signal is delivered whose action is to terminate the current process or to call a signal handling function. If a child as requested by pid has already exited by the time of the call (a so-called "zombie" process), the function returns immediately. Any system resources used by the child are freed. Please see your system's waitpid(2) man page for specific details as to how waitpid works on your system.
pcntl_waitpid() returns the process ID of the child which exited, -1 on error or zero if WNOHANG was used and no child was available
The value of pid can be one of the following:
Таблица 1. possible values for pid
< -1
- wait for any child process whose process group ID is equal to the absolute value of pid.
-1
- wait for any child process; this is the same behaviour that the wait function exhibits.
0
- wait for any child process whose process group ID is equal to that of the calling process.
0
- wait for the child whose process ID is equal to the value of pid.
Замечание: Specifying -1 as the pid is equivalent to the functionality pcntl_wait() provides (minus options).
