Using calldll with mciSendString

[Nikolai Kirsebom]

Got the first part working.  Problem was the name of function is not
"mciSendString" but "mciSendStringA".  Below part which works.  Still
working on the callback stuff.

---------------------------------------------------------
from dynwin import windll
winmm = windll.module('winmm')

def Send(s, cb=None):
    mciSendString=windll.calldll.get_proc_address(winmm.handle,
"mciSendStringA")
    bufIn=array.array('c', s + '\0')
    bufOut=array.array('c', '\0' * 128)
    ret=windll.calldll.call_foreign_function(mciSendString, 'wwLL', 'l',
                                             (bufIn, bufOut, 128L, 0L))
    s = bufOut.tostring()
    if s.index('\0') > 0:
        s = s[0:s.index('\0')]
    else:
        s = ""
    return (ret, s)
