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 it's exit code.
If you have open pipes to that process, you should
fclose()
them prior to calling this function in order to avoid a
deadlock - the child process may not be able to exit while the
pipes are open.
