-Lookup from threads
-==============================
-
-This example shows how to use unbound module from a threaded program.
-In this example, three lookup threads are created which work in background.
-Each thread resolves different DNS record.
-
-::
-
- #!/usr/bin/python
- from unbound import ub_ctx, RR_TYPE_A, RR_CLASS_IN
- from threading import Thread
-
- ctx = ub_ctx()
- ctx.resolvconf("/etc/resolv.conf")
-
- class LookupThread(Thread):
- def __init__(self,ctx, name):
- Thread.__init__(self)
- self.ctx = ctx
- self.name = name
-
- def run(self):
- print "Thread lookup started:",self.name
- status, result = self.ctx.resolve(self.name, RR_TYPE_A, RR_CLASS_IN)
- if status == 0 and result.havedata:
- print " Result:",self.name,":", result.data.address_list
-
- threads = []
- for name in ["www.fit.vutbr.cz","www.vutbr.cz","www.google.com"]:
- thread = LookupThread(ctx, name)
- thread.start()
- threads.append(thread)
-
- for thread in threads:
- thread.join()
