Off the top of my head, if you issue a blocking read, and it gets interrupted, it will either return -1 and errno will be == EINTR or it will return the data already read. Hence you should always check to see if you got what you expected. If it's a non-blocking read, then the same applies, but you should definitely be equipped to handle partial reads (see the man page "man 2 read" for more info, or the libc info pages). Note that you can set things up so that interrupted system calls restart themselves rather than returning with an error, but I don't recall at the moment which function does that. -- Rob Browning <[EMAIL PROTECTED]> PGP fingerprint = E8 0E 0D 04 F5 21 A0 94 53 2B 97 F5 D6 4E 39 30 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
