Overwrite) in WideCharToMultiByte when calling Socket API
gethostbyname CAUSEPurify validates the input parameters to the WideCharToMultiByte function call. In this case, there is an input string with a
known length and an output buffer that is big enough for the conversion.
However, there is another (sixth) input paramter to specifify the size of the
output buffer. This size is set to the maximum string size for simplicity.
Purify tries to validate the buffer for the full size instead of the actual
size.RESOLUTION This error message does not cause a problem; you can safely
