[issue12476] ctypes: need example how to pass raw data from Python

[anatoly techtonik]

New submission from anatoly techtonik <techtonik at gmail.com>:

ctypes documentation lacks an example, how to pass a raw data block from Python to a C function. For example, how to pass this chunk:

data = open('somefile', 'rb').read()

to this function:

int checkBuffer(LPSTR lpData, DWORD dwBufferLength);

?
