Question

What’s the syntax for adding binary array to a BSON with C++ driver? I’m sure it’s somewhere in the docs, but can’t find it.

From http://groups.google.com/group/mongodb-user/browse_thread/thread/b836032ad24dc00d

To create a BSONObj in C++ that stores binary data, you can do something like:

BSONObjBuilder builder;
b.appendBinData ("fieldname", datasize, BinDataGeneral, data);
BSONObj obj = builder.obj();
