&warn.undocumented.func;
The wait function suspends execution of the current process until a
child 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 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 wait(2) man page for
specific details as to how wait works on your system.

<function>pcntl_wait</function> returns the process ID of the child which
