| The WSAStartup function returns zero if successful. Otherwise, it returns one of the predefined error codes. |
|
|
| Usage: |
|
#DEFINE WSADATA_SIZE 398

* ...
= WSACleanup()
|
|
|
| My comment: |
|
MSDN: An application cannot call WSAGetLastError to determine the error code as is normally done in Windows Sockets if WSAStartup fails.
