interactive mode in python with ctypes???

[digitnctu]

Dear all:

I am coming with problem, to apply ctypes under interactive mode
in python.

libdll.dll is a third-party library. The below code segment will
run well under the batch mode(ie. python test.py 11060)
but when I type sequencially it doesn't work as usual. Can any
give me a hand??

# file test.py begin
from ctypes import *
lib = CDLL("libdll.dll")
def evCb(ev, clData, caData):
print "event: ", ev,"=>" , string_at(caData)

def run(port):
libinf = lib.libCreate(0)
lib.libConnect(libinf,port,0,0)
evfptr = CFUNCTYPE(None,c_char_p, c_void_p,c_void_p)
lib.libCltAddEventCallback(libinf,"AllEvents",evfp tr(evCb),0)
result = c_char_p()
libbuf = raw_input("lib>")
while libbuf != "quit":
lib.libCallCommand(libinf,libbuf,0,pointer(result) )
print "result: ",result.value
if libbuf == "Exit":
break
libbuf = raw_input("lib>")
lib.libDestroy(libinf)
if __name__ == "__main__":
import sys,string
run(string.atoi(sys.argv[1]))
# file test.py end

I type in interactive mode of python as below:

from ctypes import *
lib = CDLL("libdll.dll")
def evCb(ev,clData,caData):
print "event: ", ev,"=>" , string_at(caData)
libinf = lib.libCreate(0)
lib.libConnect(libinf, 11060, 0,0)
evfptr = CFUNCTYPE(None,c_char_p, c_void_p,c_void_p)
lib.libCltAddEventCallback(libinf,"AllEvents",evfp tr(evCb),0)
result = c_char_p()
lib.libCallCommand(libinf,"somecmd",0,pointer(resu lt))
lib.libDestroy(libinf)

Define "doesn't work as usual"; at least describe what actually happens
and what you expected to happen instead. If you get an exception, post the
full traceback.

run(string.atoi(sys.argv[1]))

string.atoi is deprecated eons ago; use int() instead

"doesn't work" means there is no result without exception. The python
interpretter still run without complains; but when running under batch
mode it run as the expectation. Are there difference for python
interpretter between batch mode and interactive mode ?

Thanks for Gabriel.

You should get it to work with this loop (from run()):
while libbuf != "quit":
lib.libCallCommand(libinf,libbuf,0,pointer(result) )
print "result: ",result.value
if libbuf == "Exit":
break
libbuf = raw_input("lib>")

Thanks for Gabriel.

sorry, I explain more precisely.
"No result" means the callback function evCB will not be called as
it in batch mode.
For callback function, are there difference for python interpretter
between batch and interactive mode ?
