I am able to get Segments start address, end address and all functions of a DLL through follwoing ida python script:# Get the segment's starting address    ea = ScreenEA()    print(ea)    print(SegStart(ea),SegEnd(ea))    callers = dict()    callees = dict()    # Loop through all the functions    for function_ea in Functions(SegStart(ea), SegEnd(ea)):        f_name = GetFunctionName(function_ea)        print(f_name)        # Create a set with all the names of the functions calling (referring to)        # the current one.        callers[f_name] = Set(map(GetFunctionName, CodeRefsTo(function_ea, 0)))        # For each of the incoming references        for ref_ea in CodeRefsTo(function_ea, 0):            # Get the name of the referring function            caller_name = GetFunctionName(ref_ea)            # Add the current function to the list of functions            # called by the referring function            callees[caller_name] = callees.get(caller_name, Set())            callees[caller_name].add(f_name)    # Get the list of all functions    functions = Set(callees.keys()+callers.keys())    total_callees=0    # For each of the functions, print the number of functions calling it and    # number of functions being called. In short, indegree and outdegree    for f in functions:        print('%d:%s:%d' % (len(callers.get(f, [])), f, len(callees.get(f, []))))        total_callees+=len(callees.get(f,[]))    print(\nTotal callees of \t+idaapi.get_root_filename()+\t: +str(total_callees))Script is working well when invoked inside IDA pro but if it is invoked through command prompt like below:idaq.exe -A -SC:\xxx\segment.py C:\fff\yy.dllThe output is different as below:4294967295(4294967295L, 4294967295L)    Total callees of    yy.dll  : 0
Segments start address is different in IDApython when invoked thrg cmd prompt
