Content
The way socket timeouts are implemented is by using select() to determine whether the socket is ready for read/write. In this case, select() probably marks the socket ready even though the queue is full, which later raises EAGAIN. About SO_SNDTIMEO and SO_RCVTIMEO, POSIX says "it is implementation-defined whether the SO_SNDTIMEO option can be set". Also, they would not necessarily apply to other operations such as accept().
