Python pointer to unicode string

Question

I am new to python, in fact i am just using it for IDA pro script making, so its fairly easy to understand but i am struggling to convert a long type to a unicode string, here is a snippet of my script:

def get_ModAddr(list, modname):
    flink = Dword(list)
    original = Dword(list)
    while True:
        pbasename = Dword(flink+0x30)
        ############################################################
        # pbasename now is type long and points to a UNICODE string
        ############################################################
        if modname == pbasename:
            return Dword(list+0x18)
        flink = Dword(flink)
        if ((flink == original) or (flink == BADADDR)):
            break
    Message("Could not find module.")
    return None


#DO ALL
list = get_PsLoadedModuleList()
if list:
    print "PsLoadedModuleList: %x"%(list)
    modname = unicode("DHSD.sys")
    print "Searching for module %s"%(modname)
    modaddr = get_ModAddr(list, modname)
    if modaddr:
        print "module addr: %x"%(modaddr)

So what i want to do is to convert reference "pbasename" (type long) to UNICODE string and compare it with the "modname" reference to see if they are equal.

Thanks.

I believe what you're looking for is

GetString(pbasename, -1, ASCSTR_UNICODE)

assuming pbasename is a pointer to the memory location of the unicode string. Note that this returns a string of type 'str' (not unicode) so you wouldn't have to convert modname to unicode.
