I call this script file, but got an error.

Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Program Files\IDA\python\init.py", line 60, in runscript
execfile(script, globals())

File "c:\Program Files\IDA\python\idaapi.py", line 12140, in bin_search
return _idaapi.bin_search(*args)
TypeError: in method 'bin_search', argument 3 of type 'uchar const *'

Any ideas?
