Error in pointer arithmetic (OpenCL) -

can explain me why code doesn't work?

__kernel void foo(__global const void* a) { __global const uchar* currentposition = (__global uchar*) a; // update position currentposition += 4; }

when seek read value of currentposition after increment same result when don't arithmetic.

why happening?

thank you.

it's 'const' keyword declare currentposition. c++ not allow modify values. set currentposition when declare it.

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...
