After the connect() returns EINPROGRESS, and after the select() indicates 1 descriptor ready for write, getsockopt() returns status=0, errno=0:
status = getsockopt(sockfd,SOL_SOCKET,SO_ERROR,&error,&len);
getsockopt() returns 0 on successful retrieval of the option value. So that's good.
The option value is stored in memory pointed to by the fourth parameter (named 'error', above). Hence the variable error == ECONNREFUSED.
Yes, it does indeed return ECONNREFUSED, errno = 61, "Interrupted system call" into my error variable! (I thought it would also set errno, but it doesn't.) Thanks; this is exactly what I was looking for! -Carl _______________________________________________ Do not post admin requests to the list. They will be ignored.
