linux - How to pass new messages to the thread function on run time? -

in pthread_create can specify 1 message, on run time may new messages need passed thread printing.

one way may create global vector, , maintain on adding messages it. thread fetch vector , scan new messages. in way n vectors have created n threads! or 1 construction threadid, message, , print status.

what possible practical ways out?

edit 1:

is next design fine or needs improvements?

the next code written in normal function called main().

check if thread (responsible grabbing message) there.

if yes, force message in thread's queue, wake thread (pthread_cond_signal()). if no, create thread, create queue, force message in queue.

when thread finishes reading messages in queue, allow sleep (pthread_cond_wait()).

google 'pthreads producer consumer queue'. should not need scan new entries - producer/s signal consumer thread new entries available.

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...
