iphone - BSD sockets and timeouts in iOS -

i setup socket alternative this:

struct timeval tv; tv.tv_sec = 0; tv.tv_usec = 0; if (setsockopt(sockfd, sol_socket, so_rcvtimeo, &tv, sizeof(tv)) == -1) { perror("setsockopt"); exit(1); }

when socket blocks forever on recv phone call when set tv_usec 1 socket timesout expected. expected behavior? help in understanding appreciated.

from official posix.1 manual page:

the default alternative value zero, indicates receive operation not time out.

so if set timeout 0 same default no timeout.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
