A couple more DVB CA IOCTL questions have occurred to me, and need cleared up:
1) Should the CA_GET_MSG and CA_SEND_MSG ioctls block? Currently the read()/write() interface blocks if there isn't any data/enough buffer space for the message. My feeling is no, and I should return -EAGAIN (or equivalent) for the IOCTLs. 2) Should CA_GET_MSG receive from ANY slot/connection (i.e. overwrite any user passed parameters), or should it only receive from the slot/connection supplied in the sructure. I ask this because the read() interface just returns packets from all slots/connections. My feeling is it should be possible to select, but also to specify ANY (e.g. pass -1 for either parameter). In this case, the parameter(s) in the ca_msg_t structure will be overwritten with the appropriate value. This kind of filtering is very easy with the kernel data structures I've defined. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
