fcntl(fd, F_GETFL) returns the flags as the return value, not via a passed
* camel-tcp-stream-raw.c (stream_getsockopt, stream_setsockopt): * camel-stream-fs.c (stream_read, stream_write): * camel-remote-store.c (socket_connect): fcntl(fd, F_GETFL) returns the flags as the return value, not via a passed in pointer. And F_SETFL looks for an int, not a long, and you have to pass it what it's expecting because it's a va_arg parameter. (Yes, the man page lies on Linux. But check the UNIX98 spec or the glibc source.) Also, fix another bug in socket_connect: if we manage to connect right away, unset O_NONBLOCK so it doesn't mess us up later. Fixes a bunch of problems with non-blocking I/O being done in the allegedly-blocking case and then returning EWOULDBLOCK. svn path=/trunk/; revision=7555
