Hi, I want to use external buffer in Rados::write() and Rados::read() in my application, I figure out the way on write() but I couldn't on read().
I have "char *buf" as buffer, and it's length "int len". On write(), I could do it like this: rados.initialize(0, NULL); rados.open_pool(bucket, &pool); bl.push_front(ceph::buffer::create_static(len, buf)); rados.write_full(pool, oid, bl); But on read(), I tried slimier code but fails: r = rados.initialize(0, NULL); r = rados.open_pool(bucket, &pool); bl.push_front(ceph::buffer::create_static(len, buf)); rados.read(pool, oid, 0, bl, 0); It seems new buffer allocated inside of read() operation, and the data wrote on new buffer instead of "buf". Where that new buffer allocated? And is there a way to use external buffer instead of new buffer? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
