• File src/http_socket.c — part of check-in [31d274d02e] at 2018-07-11 19:46:54 on branch smtp — Fix the socket_receive() function so that it compiles on systems that lack the MSG_DONTWAIT macro (Windows). Such systems lose non-blocking capabilities, but they work otherwise. (user: drh size: 6936) [more...]
