Error handling on Socket errors?

4 posts in this topic

#1 ·  Posted (edited)

Today I've received an error from some code using TCPConnect, namely WSANOTINITIALISED. The AutoIt help file refers to MSDN for error reference, and that is fine - except for this code. Because WSANOTINITIALISED should not be the error returned. WSANOTINITIALISED is caused by an unhandled failure of WSAStartup. According to MSDN, failure codes returned by WSAStartup should be handled on return. It even says that "A call to the WSAGetLastError function is not needed and should not be used."

The help article on TCPConnect also mentions a WSAGetError function. But this function does not exist. I assume this refers to WSAGetLastError.

Edit: Turns out something was wrong on my end. Everything works as expected now ;) .

Considering the documentation for TCPStartup mentions WSAStartup return value, I would guess the implementation is correct.

Failure:0 and sets the @error flag to non-zero.
@error:Windows API WSAStartup return value (see MSDN).

 You did use TCPStartup right?

Yes, it did not return any error. However, I can't reproduce this issue anymore, so I guess this thread is solved :D .

Classic restart solves everything. I always use the rule of 3^3, in which that determines how many times I try before I figure it's not my fault.
