proc_close

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

proc_close — Close a process opened by proc_open() and return the exit code of that process

Опис

proc_close(resource $process): int

proc_close() is similar to pclose() except that it only works on processes opened by proc_open(). proc_close() waits for the process to terminate, and returns its exit code. Open pipes to that process are closed when this function is called, in order to avoid a deadlock - the child process may not be able to exit while the pipes are open.
