Hi, using "ioctl (socket, FIONREAD, &readsize)" I can get how much is available to read from the socket using TCP. Is there a equivalent option for DCCP? I used this with DCCP and I got: ioctl failed: invalid argument Leandro. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
