Hi All,

I have a query. I am using winsock functions in my project. Most of the winsock function calls return more than one possible error codes. I want to send all possible error codes to the caller in order to display the appropriate error message to the user.

So please suggest a better way to return multiple error codes here?

Thanks in advance !

There is a list of Windows Sockets Error Codes here[^] why don't you use it (or, better, the one in your current Winerror.h file)?

i think you can use pointer array to return Multiple error codes. If you can post your code here we can help you in much better way.

Solution 3

There's a number of ways to accomplish this:

1. Return structure (to return multiples, they can be a linked list).
2. Return array.
3. Return simple error code and use a GetErrors() or GetLastError() type of routine to get details.
