proc_close — Close pipes to a process opened by proc_open(), wait for it to terminate, and return its exit code
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.
Returns the termination status of the process that was run. In case of
an error, -1 is returned.
Nota: If PHP has been compiled with --enable-sigchild, the return value of this function is undefined.

proc_close() now returns the correct exit code
even after proc_get_status() was called first.
Previously, -1 was returned in that case.
