What version of ctypes are you running?  I can't test this code (win32), but I 
just downloaded ctypes current (0.9.6), and a quick grep does show that 
function in a LOT of places:

abdul[ctypes-0.9.6]> egrep -rn create_string_buffer *
ctypes/__init__.py:43:def create_string_buffer(init, size=None):
ctypes/__init__.py:44:    """create_string_buffer(aString) -> character array
ctypes/__init__.py:45:    create_string_buffer(anInteger) -> character array
ctypes/__init__.py:46:    create_string_buffer(aString, anInteger) -> 
character array
ctypes/__init__.py:62:##    "deprecated, use create_string_buffer instead"
ctypes/__init__.py:64:##    warnings.warn("c_buffer is deprecated, use 
create_string_buffer instead",
ctypes/__init__.py:66:    return create_string_buffer(init, size)
ctypes/decorators.py:13:...     buf = create_string_buffer(256)
docs/tutorial.stx:232:    blocks, ctypes has a 'create_string_buffer' function 
which creates these in
docs/tutorial.stx:238:      >>> p = create_string_buffer(3)      # create a 3 
byte buffer, initialized to NUL bytes
docs/tutorial.stx:241:      >>> p = create_string_buffer("Hello")      # 
create a buffer containing a NUL terminated string
docs/tutorial.stx:246:      >>> p = create_string_buffer("Hello", 10)  # 
create a 10 byte buffer
docs/tutorial.stx:254:    The 'create_string_buffer' function replaces the 
'c_buffer'
docs/tutorial.stx:454:      >>> s = create_string_buffer('\000' * 32)
NEWS.txt:30:    Both create_string_buffer and create_unicode_buffer can now be
unittests/test_unicode.py:102:            buf = 
ctypes.create_string_buffer(u"abc")
unittests/test_unicode.py:106:            buf = 
ctypes.create_string_buffer(u"ab�")
unittests/test_unicode.py:110:            buf = 
ctypes.create_string_buffer(u"ab�")
unittests/test_memfunctions.py:6:        a = create_string_buffer(32)
unittests/test_memfunctions.py:16:        a = create_string_buffer(32)
unittests/test_buffers.py:7:        b = create_string_buffer(32)
unittests/test_buffers.py:12:        b = create_string_buffer("abc")
unittests/test_buffers.py:20:        b = create_string_buffer(u"abc")


Perhaps you could try updating ctypes, and seeing what happens.
