Q180222 WaitNamedPipe and Error 253 in Windows 95
In Windows 95, when WaitNamedPipe fails because of an invalid pipe name passed as the first parameter, GetLastError returns Error 253, which is not listed as a possible error code for this function. When you run the same code on Windows NT 4, the error code 161 (ERROR_BAD_PATHNAME) appears. To work around the problem, resolve Error 253 the same way as Error 161, ERROR_BAD_PATHNAME.
