There are 11 pointers, so on a 64-bit machine, we copy 88 bytes. I'm not really worried about execution time on a little-used function like OCSetPlatformInfo. I concerned about reactions similar to Gabriel's, where people evaluating our API think we're ignorant and judge the stack.

Seeing a structure passed by value is just ... ugh. Depending on the size, it's acceptable. The rule of thumb is 16 bytes. See http://www.macieira.org/blog/2012/02/the-value-of-passing-by-value/ (I've been asked to write "the reference on passing by reference" and "pointers on passing by pointer", but never got around to it) -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ iotivity-dev mailing list iotivity-dev at lists.iotivity.org https://lists.iotivity.org/mailman/listinfo/iotivity-dev
