proc_close Close a process opened by proc_open and return the exit code of that process &reftitle.description; intproc_close resourceprocess 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. &reftitle.parameters; process The proc_open resource that will be closed. &reftitle.returnvalues; Returns the termination status of the process that was run. In case of an error then -1 is returned. ¬e.sigchild;
