WSAGetLastError
The Windows Sockets WSAGetLastError function gets the error status for the last operation which failed.
int WSAGetLastError (void);
Remarks
This function returns the last network error that occurred. When a particular
Windows Sockets function indicates that an error has occurred, this function
should be called to retrieve the appropriate error code. This error code may be
different from the error code obtained from getsockopt SO_ERROR.
A successful function call, or a call to WSAGetLastError, does not reset the error code. To reset the error code, use the WSASetLastError function call with iError set to zero.
This function should not be used to check for an error value on receipt of an
asynchronous message. In this case, the error value is passed in the lParam field of the message, and this may differ from the value returned by WSAGetLastError.
Return Values
The return value indicates the error code for this thread's last Windows
Sockets operation that failed.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
