I tried adding an API handler by adding: C:\speakeasy-master\speakeasy\winenv\api\usermode\msvcp140.py using this documentation: https://en.cppreference.com/w/cpp/io/basic_ios/basic_ios

from .. import api

class basic_ios(api.ApiHandler):
    """
    Implements exported functions from msvcp140.dll
    """
    name = 'msvcp140'
    apihook = api.ApiHandler.apihook
    impdata = api.ApiHandler.impdata

    def __init__(self, emu):
        super(basic_ios, self).__init__(emu)
        super(basic_ios, self).__get_hook_attrs__(self)

and get the same error:

Did I implement the API handler correctly?

Update:
I noticed that basic_ios is not in MSVCP140. It is in MSVC170 https://learn.microsoft.com/en-us/cpp/standard-library/basic-ios-class?view=msvc-170
